Cellular frequency bands allocated to Malaysia mobile network operators

The telecommunication spectrum assignment in Malaysia is handled by Malaysian Communications and Multimedia Commission (MCMC).

Mobile network operators (MNOs) need to pay multi-million ringgit to MCMC in order to get the spectrum assignment in specific frequency band, so that they can provide cellular mobile service to customers with their assigned frequency bands.

The customers' device need to be able to communicate on the same band with the cellular transmitter at the nearby telco tower of the mobile service provider in order to establish a connection for voice and data transmission.

SIRIM is the certification body who will test and certify the mobile devices sold in the local market are complying to the spectrum used in Malaysia.

Current allocated frequency bands to MNOs in Malaysia are as below. Note that the mobile operator might not make use of all of their allocated frequency bands. In fact, most of them are not using the 900MHz band for 2G GSM.

Lower frequency means longer wavelength. This will have better in-house penetration and also able to reach a longer distance, but the bandwidth is lower and connection speed is slower.

Higher frequency means shorter wavelength. This can carry more bandwidth and also provide faster connection speed, at the trade-off of poorer in-house penetration and shorter coverage distance.

LTE frequency bands are numbered according to either the FDD specification or the TDD specification. For example, FDD Band 5 used by Unifi Mobile has a low frequency of 850MHz, therefore the LTE connection speed in this band is generally slower than those in FDD Band 3 (1800MHz).

Android mobile device users can install an app called LTE Discovery by Simply Advanced to have realtime information about which LTE band the device is connected to, as well as the signal strength, cellular tower position, and many other related information.

Tourists bringing mobile phone and/or tablet to Malaysia can check the table above with their own device specification on 2G/3G/4G to ensure that their device can function well in Malaysia, either using roaming or a SIM card purchased in Malaysia from one of the MNOs or MVNOs.

Hotlink Postpaid Flex plan by Maxis

Hotlink Postpaid Flex is a postpaid (not prepaid) mobile plan operated by Maxis.

At a monthly fixed cost of as low as RM30, you can get unlimited voice calls, unlimited SMS and 1GB of high speed data usage. After the data quota used up, you can still use the Internet at capped speed for no additional charge.

On top of the base plan, you can buy monthly auto-renewed or single month one time bundle(s), which provides you categorized apps-based unlimited high-speed Internet access:

• Unlimited Social (RM10) - Facebook, Instagram, Snapchat, Pinterest & Twitter.
• Unlimited Music (RM10) - Spotify, Joox, Saavn, KK Box & Smule.
• Unlimited Chat (RM5) - WeChat, WhatsApp, Line, IMO, QQ & IM.

These apps-based unlimited Internet access bundles are sharable via mobile hotspot tethering, although the tether speed will be capped at 5Mbps.

Additional high speed Internet quota can also be purchased as Internet pass with the current rate as follow:

• 2GB for RM10 (valid until next billing cycle)
• 1GB for RM3 (valid for 1 day)

However, only the base Internet plan can be tethered, and these additional Internet pass cannot be tethered to share with other devices.

If you need more high speed data in your base plan, you can switch your plan to:

• RM30 plan = 1GB high speed Internet + unlimited calls + unlimited SMS
• RM40 plan = 5GB high speed Internet + unlimited calls + unlimited SMS
• RM60 plan = 10GB high speed Internet + unlimited calls + unlimited SMS

When you subscribe or switch to the RM60 plan called Hotlink Postpaid Flex Plus, you can buy the following phones with 24 months contract with very attractive price:

• Vivo Y81i @ RM1 only
• Vivo Y85 @ RM199
• Vivo Y95 @ RM399

Note that these are mid-range Android smartphones, which performance is not comparable with high end or flagship smartphones.

You can install the Hotlink Flex app available in Google Play Store or iTune App Store to manage your account and monitor your high speed Internet data usage.

Note that the app for this Hotlink Postpaid Flex plan is called Hotlink Flex, not the other Hotlink RED (for Hotlink prepaid users) or MyMaxis (for Maxis postpaid users).

Inside the Hotlink Flex app, there are also quite a number of hot deals containing discount e-voucher as a kind of benefit to its users.

Note that as this is a postpaid plan, Maxis will charge you RM10/month to send itemized paper statement to your address. This is considered pretty expensive. Even if you opt for the summarized paper statement, it will also cost you RM5/month.

You can eliminate this monthly charge by opting for eBill to have your monthly statement sent to your email address instead. eBill is free of charge. You can switch between eBill and paper statement inside the Hotlink Flex app.

You can also set up Direct Debit to have Maxis auto-charge your credit card for monthly payments, so that you don't have to worry about handling your monthly payment. Hotlink Flex app contains a direct web link for you to manage your Direct Debit instruction, which you can register, change credit card, suspend, reactivate or terminate your Direct Debit with Maxis.

To subscribe or port in to this Hotlink Postpaid Flex plan, you will need to visit a Maxis Store. Your SIM card will be given to you on the spot. If there is available stock for the Vivo phone and you are subscribing to the Hotlink Postpaid Flex Plus plan with contract, you can also straight away carry your phone back from the shop.

This is quite a cost effective plan, especially for those who can make good use of the unlimited calls and unlimited SMS (e.g. businessman, sales person, agent, remote support person, etc. who needs to make a lot of calls and/or SMS every month). After all, Maxis is still the industry leader with good and stable 2G/3G/4G network coverage and speed that you can rely on.

Unifi Mobile #bebas prepaid with no credit reload expiry

It seems that Webe Digital (formerly known as Packet One or P1) had taken a long time to keep on pivoting their mobile service from P1 4G to Webe to Unifi Mobile, until recently, they seems to find some light at the end of the tunnel after the launching of Unifi Mobile #bebas prepaid plan in January 2018.

However, this prepaid plan has become less and less attractive. Initially when it was newly launched, it provided each subscribers with up to 5 free SIM cards, in which each SIM card preloaded with free 20GB of LTE data, 10 minutes voice call and 10 SMS.

Soon, it changed to provide each subscribers with up to 3 free SIM cards only, and each SIM card preloaded with free 10GB of LTE data, 10 minutes voice call and 10 SMS.

Now, it has changed to provide each subscribers with only 1 free SIM card, and the SIM card preloaded with free 10GB of LTE data, 50MB of 3G/LTE data, 10 minutes voice call and 10 SMS. Soon, the SIM card might cost you RM10, and the bundled LTE data might be further reduced to 2GB only.

In order to subscribe to this Unifi Mobile #bebas prepaid plan, you will need to download and install the Mobile@Unifi app from Google Play Store or iTune App Store, then order your SIM pack from inside the app.

During the SIM ordering process, you can either select a new number or port-in an existing phone number from another telco's existing plan. You can also select to collect your SIM pack for free at your chosen TMpoint outlet, or to have your SIM pack courier to you at the cost of RM10.60.

What makes this Unifi Mobile #bebas prepaid plan attractive?

• You can get a beautiful phone number (or port-in your existing phone number) and start using it without paying a single sen.
• You can port out the beautiful phone number to your preferred telco later, to get a better service.
• If you prefer to stay with the plan, unlike other prepaid plan with fixed weekly or monthly reload commitment, your reload in this plan does not expire. This means your next reload has no time limit, and you can perform the next reload only after you have used up all the existing quota.

Anyhow, you need to keep your SIM card active at least once in every 90 days, otherwise your number could be terminated.

To keep your SIM card active, just perform any one of the following actions, and your 90 days deadline counter will be zerorized and recalculated from scratch:

• Make a call to any number
• Send an SMS to any number
• Connect to the Internet and use some data
• Top-up your plan with at least RM10

Unifi Mobile is using its own ex-P1/Webe 4G LTE infrastructure, which has limited coverage, and running on LTE Band 5 (B5, 850MHz band). It is also riding on Celcom 3G and LTE infrastructure to obtain a much wider coverage, which is crucial to provide usable service to its subscribers nationwide.

This has made their plan a little bit complicated. Their data usage quota is separated from own Band-5 LTE (listed as LTE only in the subscription options) and Celcom network (listed as 3G/LTE in the subscription options).

For 2GB, 4GB and 8GB high speed data top-up, you get 50% of the top-up data for their own Band-5 LTE usage, another 50% for Celcom 3G/LTE usage. If you are connected to their own tower, you consume your data quota under LTE; If you are connected to Celcom tower, you consume your data quota under 3G/LTE.

Unlike other telcos which provide free unlimited capped basic data, you need to pay for the basic data in this Unifi Mobile prepaid plan. You can connected to the Basic Data either using 2G/3G or LTE, with a capped maximum speed.

Note that beside the ordinary non-expiry data reload options, there are also some unlimited data reload options with expiry (2 hours, 24 hours, 7 days) for you to subscribe whenever you need to consume a lot of data usage during certain specific occasions.

The voice call and SMS subscriptions are more straightforward, and both of them are bundled together.

Currently there are only 2 types of subscription available:

• 200 minutes call + 200 SMS for RM30
• 60 minutes call + 60 SMS for RM10

You can consider the SMS as free bundle to the voice call minutes, and each voice call is costed at 15 sen (for 200 minutes) and 16.67 sen (for 60 minutes) respectively.

This is considered pretty attractive, because for normal postpaid plans, unused voice call minutes and SMS will be burnt every month, and for normal prepaid plans, you got to keep on top-up every week or every month in order to keep the unused voice call minutes and SMS, or else all the accumulation of them will be burnt in one go.

For this Unifi Mobile #bebas prepaid plan, 15 sen per minute is really 15 sen per minute, there is no restriction of when you use it. There is no commitment to pay monthly or to periodically top-up a minimum amount, until it is fully used up, as long as you remember to keep your line active (you got plenty of SMS, just simply send out one SMS every quarter will be able to keep your line active).

As such, this Unifi Mobile #bebas prepaid plan might be suitable for you if you are:

• trying to get a free beautiful new mobile number.
• planning to use it for tablet that connects to WiFi most of the time.
• planning to use it for secondary phone with low usage.
• planning to use it for mainly receive calls and/or SMS.
• an elderly person who most of the time stays at home with Unifi broadband subscription (with WiFi, IPTV and DECT phone), so you only need to use your mobile phone when you are not at home.
• a tourist who plans to stay in Malaysia for at least a few days, up to 3 months, and wants to get a free SIM card with free 10GB data, together with minimal bundled voice minutes and SMS. (you don't need to pay for it, until you need to top-up after fully used)
• a person who finds that Unifi Mobile #bebas prepaid plan is able to provide flexibility and freedom to pay for your actual use, without monthly payment or periodic top-up commitment.

You can easily toggle on/off the IDD and roaming service of your SIM card from within the Mobile@Unifi app setting.

It is advisable for you to turn OFF both IDD and roaming unless you need to use them. This is because if you use them (either intentionally or accidentally) without prior subscription to an IDD and/or roaming pass, you will be charged on Pay As You Use (PAYU) basis which could burn your wallet a big hole. The rate of IDD and roaming pass in Unifi Mobile is on par with most other postpaid/prepaid plans, not so attractive either. The IDD and roaming pass in Yoodo has more attractive price.

Yoodo - mobile service as cheap as RM3/month suitable for light usage users and backpackers

Yoodo is a mobile service provider in Malaysia operating under the umbrella of Celcom Axiata and riding on the mobile network infrastructure of Celcom.

You can't find any official outlet of Yoodo, because they operate on the Internet and prefer you to be self-service to subscribe to their mobile service, and to self-manage your mobile plan based on your actual need on monthly (30 days) basis.

Yoodo was just launched in 2018. Initially, it was not so attractive, until its data plan been reduced to cheaper price, and the quota starting from as low as 2GB/month usage @ RM12  (instead of starting from 5GB/month @ RM30 when it was launched).

Yoodo is currently one of the very few mobile service providers in Malaysia that enables you to spend less than RM30 per month in your mobile service.

You might want to seriously consider using Yoodo if you are:

• a light usage mobile user who prefers not to spend too much on your mobile plan. If you are a medium data usage user, you can opt for Hotlink Postpaid Flex instead, which provides unlimited nationwide calls and unlimited SMS, with price starting from RM30/month only (for 1GB data plan, add RM10/month to get additional 4GB/month). If you are a heavy data usage user, there are plenty of postpaid/prepaid plans available with high data quota, including those with unlimited data + unlimited calls + unlimited SMS.
• planning to maintain a beautiful mobile phone number at the lowest possible cost at RM3/month.
• planning to use it for tablet that connects to WiFi most of the time, and does not need any voice or SMS bundle.
• planning to use it for receiving calls and SMS.
• planning to use it for making calls and/or SMS, with low to medium data usage. 
• a backpacker or tourist who plans to stay in Malaysia for more than a week to a few months, and wants to get a mobile plan with cheap IDD option to receive and/or make calls and SMS to other countries.
• a backpacker or tourist who plans to visit Malaysia and some other surrounding countries, with cheap roaming option.
• a person who finds that Yoodo is able to provide flexibility and freedom to customize your own plan based on your actual need from month to month.

Yoodo plan is pretty straightforward. Its base plan consists of 3 portions: data, voice and SMS, which you can customize your usage for the month (30 days validity from day of subscription).

You can always make change to your plan for the upcoming month. So, if you know that next month your usage will be higher (for example, when going for outstation), you can subscribe a higher plan for next month, and then fall back to the lower plan the month after.

There is a GUI in Yoodo's website for you to try out how to adjust your base plan for data, voice and SMS, with the price automatically calculated for you.

The beauty of Yoodo plan is that, as long as it is still active, you can always receive phone calls and SMS, even you just subscribe a data plan and leave the subscription to voice and SMS to remain as zero.

Unlike certain data plans from other telcos which will impose restriction on hotspot tethering (mobile data sharing), there is no tethering restriction on Yoodo data subscription, be it a base plan or booster plan.

Yoodo SIM pack can be ordered online for free, and will be courier to you for free too.

Click here to order your Yoodo SIM pack and receive RM20 credit in your e-wallet when you successfully activated a plan with the SIM card.

If you need the SIM pack to be delivered to you within 2 hours, it is possible if your receiving address is in Klang Valley, and you are willing to pay for the express delivery service. This express delivery option is available when you order your Yoodo SIM pack. This will be necessary for backpackers or tourists. You can arrange for your accommodation's reception to receive the SIM pack on your behalf while you are away visiting places.

You will need an Android phone or iPhone in order to manage your Yoodo account with the Yoodo app, which you can download and install from Google Play Store or iTune App Store. Each account can manage up to 5 Yoodo SIMs.

Note that the device you use to manage your Yoodo account with Yoodo app need not be the same device which you are going to install the Yoodo SIM card. If it is the same device, then you might need to connect to WiFi to download the app and to perform SIM card activation, before you got mobile data available for use.

After you've received your SIM pack, you need to activate the SIM card inside it to start your subscription. Don't worry whether you have already customized your base plan during SIM pack ordering process or not, because you will be given a chance to customize the base plan again during the activation process.

However, if you have customized your base plan for a mobile number port-in from another telco, your base plan for the first month cannot be changed during activation. You will need to order a new SIM and start over the process for such a change.

Yes, Yoodo does support MNP (mobile number portability).

Yoodo activation process involves scanning (or manually key-in) the barcode of the SIM card, taking a photo of your NRIC or passport, taking a photo of yourself which requires you to do some action, and paying for your first month subscription by using your credit/debit card or PayPal account.

You might want to use a phone with better camera for the activation process to be smoother, because it will use OCR to scan your NRIC/passport and use face recognition AI to scan your face.

Don't forget to key-in this Referral Code during activation for you and me to get RM20 in our e-wallet respectively: cwqhp2909

After you become a Yoodo user, you will also have your own unique Referral Code to get RM20 for each referee sign-up.

Below is the Yoodo Dashboard shown in Yoodo app for you to manage your Yoodo subscription.

It will show you your current plan and usage. Don't worry when your base plan used up in the middle of the month, you can always purchase a booster plan by taping on "Buy more" to get additional quota for the month.

For example, even though I did not subscribe any voice plan for the month, if I need to make call, I can purchase a voice call booster plan to get the required quota immediately.

Note that you can buy roaming and IDD service from the above Dashboard screen too. Just follow the steps, the app will explain about the service to you clearly.

Your plan will be auto-renewed after 30 days, using the same configuration as this month unless you change it. Changes will take effect on the next cycle, and before it is effective, you can always come back and modify the configuration by tapping on "Change".

In the above screen, you can switch off the auto-renew function, and your e-wallet or linked credit/debit card or PayPal account will not be automatically charged when your current 30 days subscription cycle ended.

If you don't pay for the next month, you can still receive voice calls and SMS, but unable to access to Internet, make call and send SMS. There is a grace period for this, after that, your account will be terminated and your mobile number will be unusable.

Beside the 3 base plans of data, voice and SMS, you can also subscribe for specific app data usage add-ons, including Instagram, Facebook, YouTube, WhatsApp, and PUBG Mobile. The data usage for subscribed add-ons will be consumed first before the base data plan is deducted for the month. Note that these add-ons are not applicable for tethering.

Also note that since Yoodo is riding on Celcom network, it shares the same pros and cons, as well as strength and weaknesses, with Celcom mobile service, which you might be interested to read my another article here.

Yoodo's customer service is pretty friendly, helpful and responsive. They are contactable with Live Chat in the app and also in their website, within the operating hour from 9am to 9pm (weekdays) and from 9am to 6pm (weekends). To access to Live Chat, just go to the Help section and scroll to the very bottom of the screen, and look for this:

Beside using Live Chat, you can also fill in a web form to submit an issue ticket to them. There is also a community forum to discuss with other Yoodo users and staffs.

No doubt Yoodo's establishment and its business model has disrupted the Malaysia mobile service market. It provides a 3rd kind of mobile subscription beside the traditional prepaid and postpaid plans.

It is flexible that you can customize your plan according to your need, with booster plan to boost up your quota within a subscription cycle, so that eventually you only pay for what you need to use. It is also very easy to exit, either by MNP to another telco, or stop paying for the subsequent month and let the subscription lapses by itself.

There are also options for immediate termination and SIM card replacement, in the event of handphone lost, for example.

If you find it interesting, you can order the SIM pack for free without any obligation. Then when you want to start using it, you can customize your own plan in Yoodo app, and activate the SIM card to start your subscription.

Comparison of Maxis vs Celcom network usage experience (year 2019)

Maxis and Celcom are the 2 mobile service market leaders in Malaysia in terms of network coverage and speed. They are closely challenged by Digi and U Mobile, followed by Unifi Mobile.

This comparison is made based on my personal experience and observation by installing SIM card of different operator, one at a time, into the same SIM card slot of the same handphone, and using the handphone at the same location during the observation timeframe.

Note that only Maxis, Celcom and Digi (and their respective sub-brands) are using own 2G/3G/4G and even 5G network. Yes only has 4G coverage at limited areas. The others are somehow riding on the network of these Big 3 (mostly on Celcom), as shown in the table below.

However, based on my observation, the SIM card of the operator does play a role in your network usage experience. For example, TuneTalk and Celcom will be connected to the same infrastructure belonged to Celcom, but the way your handphone maintains the connection with their SIM card might behave differently.

Between Maxis and Celcom, I observed that Maxis provides an overall better experience, particularly when you are inside a building. This observation is made in a location which OpenSignal indicates that both their 2G/3G/4G signal at the area are equally strong.

How does Maxis achieve the better result? This is possibly due to Maxis behave differently from Celcom when the phone is in standby mode (not in phone call, no SMS in/out, no foreground open app, screen is on).

When WiFi is connected, Maxis will settle down with the most stable signal at highest strength (in terms of dBm and ASU). For layman, this will be a state which your phone get the most signal bars shown at the status bar. In my observation, unless there is background network activity ongoing, else it will settle down to 3G UMTS connection, giving a full bars or close to that. The maximum network speed at UMTS is 384 kbps only.

When WiFi is off, Maxis will immediately scale up its connection, and maintain at a balance between speed and signal strength, to provide optimal network stability. In my case, it will stay at HSPA+ with maximum speed of 42.2 Mbps. It will only reach out to 4G LTE when the phone's network activity increases, demanding higher network speed.

On the other hand, Celcom will always go for the highest generation and stays at 4G LTE or LTE+ as long as there are 2 bars of signal and above for 4G, regardless WiFi is connected or not, despite the signal at lower generation is much stronger.

U Mobile will settle down with 2.75G EDGE with maximum speed of 220 kbps, when WiFi is connected. OpenSignal showed that it connects to the same Maxis tower when Maxis was tested as above.

By connecting and staying at lower generation when WiFi is connected, it actually helps to save some battery usage.

When WiFi is connected, it seems that:

• Maxis connection will stay at the most stable signal at highest strength.
• Celcom connection will try to show off they got 4G LTE/LTE+ at the area by connecting to 4G, even though the signal is comparatively weaker than lower generations.
• U Mobile will connect to the lowest possible generation while maintaining decent connection speed.

When WiFi is disconnected and Internet is in used, it seems that:

• Maxis connection will try to strike a balance between speed and stability.
• Celcom connection will actually fall back to HSPA when LTE/LTE+ signal is too weak for stable connection, otherwise it will just stay at LTE/LTE+.
• U Mobile does not have 4G coverage at the area, since the connection never reach LTE/LTE+.

When there is an incoming phone call or SMS, it seems that:

• Maxis connection will raise from UMTS to HSPA.
• Celcom connection will drop from LTE to HSPA if the 4G signal is too weak.
• U Mobile connection will raise from EDGE to UMTS.

Due to the different in their behavior:

• When I make a call from another phone, Maxis will ring faster than Celcom. Sometimes, you will see the connection of Celcom changed from LTE to HSPA before the phone actually rings.
• When I send an SMS from another phone, it will generally reach Maxis faster than Celcom.
• The voice quality in a phone call with Maxis is generally more stable and better than Celcom.
• There is not much different between them in Internet usage, their speed is almost the same in this area, regardless connected with HSPA or LTE. The download speed is much higher than the upload speed.
• Let the phone lying overnight, U Mobile is able to conserve slightly more battery than Maxis (different for about 1% draining), which in turn conserves more battery than Celcom (different for about 2% draining).

Therefore, Maxis provides an overall better network usage experience than Celcom, in terms of battery saving, phone call quality, speed of receiving phone call and speed of receiving SMS.

Besides, there are several other reports available in the Internet about general comparison of Malaysia mobile service providers, including comparison of postpaid packages, prepaid packages, price, coverage, network speed, etc. One of the good source is OpenSignal which you can search around for their analysis reports.

The evolution of cellular mobile technology (from 1G to 5G)

Do you still remember the first generation of mobile phone running on 1G analog cellular telecommunication network? The phone is as bulky as a brick with large external antenna. The average talk time for each battery recharge is about 35 minutes only. It was a luxury item.

Mobile phones started to become popular during the 2G digital era, whereby SMS text messages were made possible. Sending SMS at that time was not as convenient as today, as the phones were having physical T9 keypad, and typing alphabets would need more than one strokes.

Apple has changed the world during 3G era by introducing iPhone supported with iTune app store. Physical keypad was totally removed from the phone, giving larger space for its touch screen.

Today we are at 4G era, moving forward to 5G soon.

The table below summarizes the evolution of cellular mobile technology from 1G to 5G. We can see that for each advancement of generation, or sub-generation in between, there would be an increase in data transfer speed, and wider range of network application usage.

5G will be essential for the IoT connected world, particularly for connected vehicles and smart cities.

5G technology promises to greatly reduce the latency (the "preparation time" required before 2 wirelessly connected device to start transmitting data to each other) to around 1 milliseconds, compared with the current 30 milliseconds in 4G LTE.

5G technology also promises a 20 times increase in network speed from 4G, bringing gigabit Internet access possible to all mobile devices.

5G technology also promises a much stable and reliable signal strength by utilizing massive MIMO beamforming technology, which is a matured technology already in used in Wireless-AC WiFi networks for years.

On the other hand, 5G will require much stronger end-to-end cybersecurity protection and user privacy protection.

Are you excited to the upcoming 5G technology? It is said that key industry players are already working on 6G, which will mesh over satellite WiFi technology.

Smart devices Li-polymer battery fast charging technology and compatibility

Nowadays, one of the selling points of smart devices (phones, tablets, watches, cameras, etc.) is how soon can they recharge their Li-polymer battery. There are already products which claim to be able to recharge from 10% to 100% within 20 minutes.

The battery charging speed is an important convenience indicator. If your mobile device can recharge its battery within a short period of time, it will greatly reduce your waiting time for its battery recharging, and also reduce the need of bringing along a power bank.

Imagine that when you are on the move and taking a short break at a place, you just need to borrow a power source for 5-10 minutes to quickly recharge your phone to bring up its battery level to be sufficient for the rest of the day, there will be less worry for you about the phone running out of battery power, and you don't need to wait for a long time for the recharging process.

The Li-polymer battery fast charging technology evolves following the evolution of USB into Type C era, and the introduction of industry standard called USB Power Delivery (USB-PD).

Traditionally, the USB cable has more emphasis on data transfer than charging function. The maximum power or Wattage (Power = Voltage x Current) a traditional USB cable and its charger can deliver is merely 2.5W.

With the current USB 3.1 standard, theoretically the maximum charging power can go as high as 100W. The more wattage the charging mechanism can deliver, the faster will be the charging process.

The charging mechanism consists of:

• The charger
• The cable
• The device (phone/tablet/etc. for non-removable battery)
• The battery

For fast charging to happen and to be safe, all the 4 charging components must be compatible and working well with each other. Otherwise, you will probably end up with traditional 2.5W slow charging, or your fast charging will be at risk of overheat, overcharge, battery damage or even device damage.

Compatible fast charging components will form a charging mechanism that can deliver stable fast charging wattage, and has electronic circuits and mechanisms to protect the battery and device from being damaged (such as catching fire, explode, bulking, malfunction, ...), overheat, overcharge, etc.

Different device manufacturer has come out with different kinds of fast charging mechanism, under different brand names such as Quick Charge, TurboPower, Pump Express, SuperCharge, VOOC, and so on.

If the device and battery is USB-PD compliance, then you can fast charge it with 3rd party or other brand of USB cable and/or charger that are also USB-PD compliance.

If the device and battery is Qualcomm Quick Charge compatible, then you can fast charge it with 3rd party or other brand of fast charger with Qualcomm Quick Charge chipset inside, using USB cable that supports 5A current transmission.

If you want to play safe, the rule of thumb is to fast charge your device using original charger and original cable from the same manufacturer designed for your device.

It seems that Oppo Super VOOC can charge its supported Oppo phones more faster than the others, however the Super VOOC charging mechanism is pretty proprietary. Huawei SuperCharge 2.0 found in its Mate 20 Pro, Mate 20X and later model of devices can also charge pretty fast at 40W, and is compatible to USB-PD and Qualcomm Quick Charge, although the wattage might be lower when fast charged with 3rd party compatible charger and cable.

Here are some tips if you want to buy a power bank, 3rd party charger or 3rd party USB cable:

• Choose the USB cable that can support 5A charging. It is backward compatible and more future proof.
• Choose the power bank that support Quick Charge 3.0 or Quick Charge 4.0+ to enable fast charging with compatible devices. Make sure it also has built-in mechanism to protect the battery and device properly. Choose for branded product that is reliable.
• Choose the wall charger that support the same charging voltage and current with your original wall charger. Make sure it also has built-in mechanism to protect the battery and device properly. Choose for branded product that is reliable.

Automate Flow: Let your phone / tablet inform you when its battery is 100% fully charged

This is an example of Automate flow. To learn more about Automate for Android phones, click here.

It is advisable to unplug your phone / tablet from its battery charging source once its battery is 100% fully charged.

Although modern Li-polymer battery has overcharge protection in its circuit and in its charger, overcharge can still happen when the battery is aged (exceeded its warranty period), or you are using 3rd party charger and/or 3rd party charging cable, which might not work well with its overcharge protection mechanism.

Some common symptoms of battery overcharged including overheat and/or battery bulking (permanent damage).

This is a simple Automate flow that lets your phone / tablet speak to you to inform that its battery is 100% fully charged, so that you are alerted and can proceed to unplug it from the charging source.

You can change the speaking voice, its pitch and speed, in your Android text-to-speech setting.

Automate Flow: Auto disable WiFi when you are travelling in a vehicle unless you are connected to a hotspot

This is an example of Automate flow. To learn more about Automate for Android phones, click here.

Normally when we are travelling in a vehicle, we have no WiFi access. Disabling the WiFi function of our Android smartphone and/or tablet will help to conserve some battery usage.

However, there might be situation when our phone/tablet is connected to a mobile WiFi hotspot which is in the vehicle. In this case, we won't want to disable the WiFi function.

Below is the Automate flow that will automatically disable WiFi when you are travelling in a vehicle, unless you are connected to a WiFi hotspot.

Online check whether handphone / tablet is genuine local original set with SIRIM MCMC Label registration

Communication products particularly handphones and tablets sold by authorized distribution channels in Malaysia are required to be certified by SIRIM under the Communications and Multimedia (Technical Standards) Regulations 2000.

Certified products will carry a genuine MCMC Label with serial number, normally stuck on the packaging box. Alternatively, it could be in the form of electronic MCMC Label stored digitally in the device, displayable on the screen normally from About page.

As such, you can know whether your handphone and/or tablet is genuine local original set by checking for its IMEI number(s) and/or Serial Number with SIRIM MCMC Label registration. If the result of the check is "not found" then your device is not registered with SIRIM, and most probably was imported from non-proper channel, or is a clone/counterfeit product.

There are 2 common ways to perform the checking online. One way is through the SIRIM e-comM enquiry website, and another is by using the SIRIM Check Your Label mobile app.

Below is the URL to check using the IMEI number of the handphone/tablet. For dual-SIM products, both IMEI numbers can be checked respectively:
https://ecomm.sirim.my/SirimEnquiry/search_IMEI.aspx

And you can download the Check Your Label mobile app from Google Play Store (for Android) and Apple iTune Store (for iOS).

The Check Your Label app will display slightly more information than the e-comM website.

 

 

Online checking for Huawei smartphone warranty period expiry and applicable country

If you have bought a new Huawei product such as a smartphone / tablet / laptop and have registered for its warranty, whereby the registration was done by your dealer or by yourself, you can actually check for its warranty information in Huawei Consumer Products website by using the serial number of your product.

You can, of course, make use of the same webpage to check whether:

• Your product has already been registered for warranty or not.
• Your product is a new set or used/refurbished set. Used or refurbished set will have warranty expiry shorter than the full warranty period.
• Your product is an original local set or non-local set.
• Your product is genuine Huawei product or counterfeit product with invalid serial number.

You just need 2 steps to perform this warranty checking.

Firstly, you need to know the serial number of your product, which is printed on the label at the packaging box.

For Huawei smartphone, the easiest way to find out your phone's serial number is by dialing *#06# which will display its serial number and IMEI number(s) on the screen. You can then long tap on the displayed serial number to copy it into your clipboard.

Another way to view the smartphone's serial number is by going to Settings > System > About Phone > Status.

Once you obtained the product serial number, open your web browser and visit to this webpage: https://consumer.huawei.com/my/support/warranty-query/

Paste or key-in your device serial number, and also enter the 4-characters captcha as verification code, then press the Search button.

For Huawei smartphone, the product warranty information page will show out:

• The product name and model number
• The product serial number
• Expected warranty expiration date
• Applicable scope
• Screen damage warranty expiration date
• Premium service expiration date

In addition, the device warranty expiration information is also available in the HiCare mobile app most probably pre-installed in the Huawei smartphone. Just open the app in the phone, tap on Me option, you'll be able to find the warranty expiration date and applicable country under the Device Benefits section.

Just tap into the Warranty and/or Screen Insurance image link to view the detail information.

Furthermore, you can continue to check whether your device is genuine local original set with SIRIM MCMC Label registration.

Releasing handphone storage space by cleaning up WhatsApp files

Have you wonder what have silently taken up your handphone / tablet storage space? I bet the top culprit will be messaging apps such as WhatsApp.

WhatsApp stores all your individual and group chatting history in your phone storage, including all the media files and documents which you've sent out and also you've received from others. Over time, it will consume up gigabits of your phone / tablet storage.

Within the WhatsApp application itself does not have any mechanism for you to clean up old files or large files in order to release your handphone storage space.

Anyhow, you can easily locate those files stored by WhatsApp in your phone by using a file manager app such as File Manager + and navigate to the /WhatsApp/Media folder in your phone storage. The files are all there! You can then manually backup and/or delete the files there.

In fact, you can also program an Automate script to perform some sort of automated WhatsApp files housekeeping to release your handphone storage periodically.

Another easier way is to make use of an Android app called Cleaner for WhatsApp by LookAndFeel Lab to do the housekeeping.

Note that there are multiple Android apps call themselves as Cleaner for WhatsApp in the Google Play Store, and I am referring to the one developed by LookAndFeel Lab with the app icon as below:

This Android app is like a specific version of file manager to release handphone storage space taken up by WhatsApp files.

It shows you the total WhatsApp files found and the total storage space taken.

According to the WhatsApp directory structure, Cleaner for WhatsApp is able to list down the number of files and storage space taken by file types:

• Videos
• Images
• Documents
• Databases
• Voices
• Audios
• Gifs
• Stickers
• Profile Photos
• WallPapers

By entering the folder, it can let you review those files that you sent to others, those that you received from others, and duplicated files.

With a single tap, you can select all the files within the category (received, sent or duplicated), or you can manually select the files one-by-one, for you to perform the delete action. The files can be sorted by size (either large size first or small size first) or date (either oldest first or newest first) to make it easy for batch selection for deletion.

The function that makes a real difference from ordinary file explorer is its auto-clean function, which you can select to periodically check for the WhatsApp file and clean them by date or by size. It provides option for you to select which types of files you want to auto-clean.

With Cleaner for WhatsApp, you are able to release quite a number of handphone storage space occupied by those WhatsApp files. I would suggest LookAndFeel Lab to also provide achieve function beside cleaning to make it even better.

Quick and effective fix for Whatsapp voice call intermittent quality problem

There are quite a lot of occasions I experienced intermittent quality problem when making or receiving WhatsApp voice call. The sound from the other party just couldn't transmit well to my phone.

This kind of intermittent situation occurred even when I was connected to 5 GHz WiFi with high speed fibre Internet access, and I was very sure that the network utilization during the call was low without any congestion at all.

After some trial and error attempts to improve the situation, I finally found out the solution to fix this WhatsApp voice call intermittent problem.

You just need to change one setting in WhatsApp, and your WhatsApp voice call will be magically turned from intermittent to very clear.

If you are also experiencing similar problem with WhatsApp voice call, try go to Settings > Data and storage usage > Call settings and enable "Low data usage".

I am not sure what does WhatsApp do behind the scene with this setting turned on, but it does magically fixed my voice call problem. It works both when using WiFi or using mobile data.

Free Android app to scan, read and generate QR codes and barcodes (ad-free)

There are quite a lot of QR code scanner in the Google Play Store nowadays. Some can also read and interpret QR code from a graphics file saved in the phone. There are also a few even capable to generate new QR code for you.

However, not all of them are free. And, most of the free one are not ad-free.

I have found one that really impress me. It is a 3-in-1 QR code scanner, reader and generator app, very simple to use, and most importantly, it is free for use and ad-free. This means it won't bombard you with any annoying ads!

This Android app is called QR & Barcode Scanner, QR Code Reader, QR Generator offered by Digital Seo Web. You can click here to download and install it from Google Play Store.

By using the phone's camera, it is able to scan and interpret most if not all QR codes and also 2D barcode types including text, website link, product, ISBN, contact, email, calendar, location, Wi-Fi, data matrix, EAN, UPC, Code39, Code128, Codabar, ITF, EAN8 and many other formats.

The app has a trigger for you to turn on your phone's flashlight during scanning environment with low light condition.

Upon successful interpreting of the scanned code, the result will be displayed on the screen, and you will be given options to open the web URL (for website link), save contact information to your phone contacts (for business card QR code), access to WiFi (for WiFi credential QR code), send it out as email, send it out as SMS, share it to other apps, or export it to a CSV file which will contain the date, type and interpreted content of the code.

This app has a very clear-cut menu.

You can read the QR code or barcode saved as PNG, JPG or other graphics file by using the Gallery function.

You can generate your own QR code by using the Generate function.

You can look back at the past scanning/reading results by using the History function.

This app is able to generate quite a number of QR code types, including personal profile, business profile, contact number, SMS message, plain text, email, website URL and company profile.

You can save the generated QR code as a JPG file in your phone by tapping on the "download" icon at the top-right corner. You can also share the generated QR code to other apps.

This app seems to be pretty new in Google Play Store, but it is really amazing. I highly recommend it for all Android phone users who are looking for a free, modest and ad-free QR code scanner, reader and generator.

ADcase the handphone case with special dampers that can save the phone from dropping damage

ADcase (active damping case) is a very innovative handphone case invented by a German engineering student called Philip Frenzel. It has just won an award from German Mechatronics Society.

The phone case has special shock-absorbers made with metal springs at its 4 corners. In normal situation, the shock-absorbers are hiding inside the case, and the case just looks like other normal handphone cases.

When sensors inside the case detected that the phone is on free fall dropping, it will immediately unfold the metal springs before hitting the ground. In this way, it can effectively protect the phone from damage due to dropping.

After the falling, the dampers can be manually folded back into the case and are therefore reusable.

You can watch the video below to see how ADcase reacts when the phone is dropping.

Very brilliant idea, isn't it?

WiFi Alliance introduced WiFi Certified WPA3 to replace current WPA2 security standard

WiFi Alliance has just introduced WiFi CERTIFIED WPA3 (Wi-Fi Protected Access version 3) as the next generation WiFi security standard, bringing new capabilities to enhance WiFi protections in both personal and enterprise wireless networks.

Key capabilities of WPA3 include:

• WPA3-Personal: more resilient, password-based authentication even when users choose passwords that is simple to remember. WPA3 will leverage on Simultaneous Authentication of Equals (SAE), which is a secure key establishment protocol between devices, to provide stronger protections for users against password guessing attempts by third parties.
• WPA3-Enterprise: offers the equivalent of 192-bit cryptographic strength, providing additional protections for networks transmitting sensitive data, such as government or finance. The 192-bit security suite ensures a consistent combination of cryptographic tools are deployed across WPA3 networks.

With the evolution of WiFi security from current WPA2 to WPA3, we can expect:

• WiFi password to be a lot more difficult to crack.
• WiFi CERTIFIED Easy Connect - IoT devices can connect to WiFi network more easily.
• WiFi data sniffed and recorded without knowing your password will not be able to decrypt even if your password is obtained later.
• WiFi CERTIFIED Enhanced Open - communication in open connection (WiFi connection without the need of any password) will also be encrypted, therefore much more secured than WPA2 open connection. In current WPA2, if the WiFi is connected using open connection without the need of password, the communication between the WiFi connected device and access point is not encrypted.
• Stronger WiFi encryption by replacing the existing PSK (Pre-Shared Key) system in WPA2 with the new SAE system.

Anyhow, in order to enjoy the benefits of using WiFi WPA3, both the access point (or wireless router) and the connecting device must support this new WiFi security standard. Devices that support WPA3 will probably hitting the market from year 2019 onwards and gradually replacing the existing which only support up to WPA2.

Automate Flow: Auto enable Bluetooth to connect to car hands-free when you are driving, else disable Bluetooth

This is an example of Automate flow. To learn more about Automate for Android phones, click here.

It is always a good idea to disable the Bluetooth function of your Android phone until you want to pair it with another Bluetooth device, such as hands-free system, GPS, audio speaker, input device (keyboard, mouse, gamepad, ...), etc. This will help to conserve some battery usage of your phone.

However, if you are always wearing a Bluetooth smartwatch that paired with your smartphone, you will need to let the Bluetooth function of your phone to always stay on. In that case, this Automate flow might not be so relevant for your need.

Nowadays, driving laws in many places in the world prohibit holding your phone in your hand while driving. If you are caught with that, you could be imposed with penalty and fine. Therefore, you need a hands-free system to answer to phone calls while driving. Many modern cars already have built-in hands-free function in their audio system. Certain automotive GPS device such as Garmin DriveAssist, Garmin DriveSmart, etc. is also able to link with your smartphone through Bluetooth to provide hands-free and some other additional functions.

Well, if you always disable Bluetooth of your Android phone and manually enable it whenever you want to pair it with a Bluetooth device, it would be very tedious if you are a frequent driver. You will need to enable Bluetooth whenever you sit in your vehicle and started its engine, and disable Blueooth whenever you parked your vehicle and stopped its engine, otherwise you will not be able to use the hands-free function. This Automate flow will help you to automatically perform those action.

In addition, normally when we are in a vehicle on the road, there is no WiFi available. This flow will also help you to disable WiFi when it detected you are travelling in a vehicle. You can edit the flow and remove the "Disable WiFi" block in it if your vehicle does provide WiFi connection that you want to use.

The flow begins with a block to stay and wait until it detected your Android phone carried along with you is travelling in a vehicle. This is a very interesting Automate block. Beside "in vehicle", it can also detect whether you or your phone is:

• On bicycle
• On foot
• Running
• Still
• Tilting
• Walking
• Unknown

It makes use of sensors of your phone to perform the guessing, and report back with a confidence level. The "in vehicle" block setting of the above flow is as below:

The flow will continue its further actions when it is at least 85% sure that you are in a vehicle. The detection interval is set at 2 minutes. If you want the flow to react faster, you can shorten this detection interval, but it might drain more battery at the same time.

Once it detected you are in a vehicle, it will disable WiFi function of your phone (Block 3).

It will then detect whether the battery level of your phone is above 30%. If it is below, whether your phone is plugged to a power source for charging. If both conditions are negative, it will disable Bluetooth and do nothing. I put 30% battery level as this should be sufficient to keep your phone on with Bluetooth paired for quite a long journey. You can adjust this minimum battery level requirement in Block 14 according to your situation. If your driving distance is most of the time pretty short, probably 15% minimum is good enough for you.

If battery level is OK, it will proceed to enable Bluetooth, wait for 10 seconds for your phone to pair with the Bluetooth device in the vehicle (which as a prerequisite, they must be successfully paired before), such as your car audio system hands-free, or your GPS. If the pairing is successful, it will keep the Bluetooth connection until it is disconnected. Disconnection will happen when your car audio system is switched off (when car engine turned off), or when you manually disable your phone Bluetooth function (in case you do not intend to use hands-free during that journey. For example, you are a passenger in your own car which one of your family member is driving for that trip).

It will wait for 3 minutes before going back to detect whether you are in a vehicle again. 3 minutes is a reasonable minimum time interval for you to leave your car and then to drive it again. That will be the estimated time to stop the car engine, pump the petrol, and resume driving. For other occasions, probably the interval is much longer. You can edit Block 13 to change this interval shorter or longer to suit your need too.

In the event Bluetooth pairing failed after the Bluetooth is enabled, you are very likely to be not in your own car, but in another vehicle either as passenger or driver. Since the hands-free function is not available to you in that vehicle, the flow will proceed to disable Bluetooth and wait for a longer 30 minutes (which you can edit Block 20 to change it to be shorter or longer). 30 minutes is an estimation that you will probably won't drive in your own car, since you are travelling in another vehicle at that moment.

In fact, you can remove both Block 13 and Block 20 and immediately go back to activity checking if you want. The 2 delay blocks are merely for the flow to take a break (and save some battery).

Automate Flow: Auto enable WiFi when you arrive home and disable WiFi when you leave home

This is an example of Automate flow. To learn more about Automate for Android phones, click here.

It is always a good idea to disable the WiFi function of your Android phone until you want to connect to a WiFi network. This will help to conserve battery usage, and also prevent your phone from automatically get connected to certain open WiFi without your aware, which might be used to hack in your phone.

Normally, there are fix places with WiFi that you will definitely want to use, to conserve your mobile Internet data quota usage. Those places include your home and/or your work place.

This Automate flow will help you to automatically disable WiFi function of your phone after your leave your home, and automatically enable it back when you arrive your home. It will even inform you by voice so that you are aware when WiFi is automatically enabled and disabled by this flow.

Enabling WiFi function does not guarantee a successful connection, because sometimes your access point (AP) or wireless router might have problem in establishing the WiFi connection.

Therefore, after enabling WiFi, this flow will wait for 10 seconds, which should be long enough for normal WiFi connection to be established. It will then check if the connection is successful or not.

If the connection is successful, it will log down the name a.k.a. SSID (service set identifier) of the AP or wireless router your phone has connected to.

If the connection is not successful, it provides option for you to remain enable WiFi or to disable it. Regardless of your selection, you will still need to troubleshoot and find out why the WiFi connection cannot be established. It could be caused by your AP or wireless router is switched off, or hang, or WiFi function disabled, or DHCP IP address allocation full, or other possible issue. If your phone has never made a successful connection with the WiFi at the location before, or you have made your phone "forget" about it, the connection will also be not successful as well.

Before you can use this flow, you need to tell it where is your home. This can be done by tapping on Block 12 "When at location". The following screen will come out.

Tap on the "Pick a location on map..." button to bring out Google map. You can then search for your home by either tapping on the "target" icon if you are currently at home, or by tapping on the search (magnifying glass) icon and key in your home address for search, or by manually selecting the location by navigating the map and tap on the targetted place.

When you are done, tap on the OK button below to capture the location's coordinate.

The Radius setting determines the area that you consider your phone is at home. Normally, 50 meter radius as shown above is a good choice. You can set its value larger so that your WiFi is automatically enabled faster when your approaching home, and automatically disabled after you have travelled further away from your home.

You can use this same flow for other places with fixed WiFi, such as your work place. Just go through the same steps able to set the location before running it. You might also want to change the word from "home" to "office" in Blocks 14, 15, 16 and 17 of the flow.

With slight modification, you can even expand this flow to be used for multiple locations.
