Celcom has just launched a new postpaid plan for smartphones with voice and data component, which has an OPTIMISER mechanism to provide flexibility for subscriber to use more data or more voice and SMS within a billing cycle.
Under the plan allocation, the subscriber is given a quota of 2 GB Internet data usage, 2 GB Celcom WiFi usage, 100 minutes voice call, and 100 SMS.
Once you have used all of your allocation above, OPTIMISER will automatically adjust to give you complimentary additional quota of either Internet or calls and SMS. You can either get an additional 2 GB of Internet data usage + 2 GB of Celcom WiFi usage, or additional of 150 minutes voice call + 150 SMS.
If your OPTIMISER allocation is also fully utilised, you will be charged 15 sen/minute for voice calls thereafter, and 15 sen per additional SMS. You can also get additional 1 GB Internet quota at the cost of RM15.
Lets compare this new Celcom First Basic plan with the existing Celcom First Prime plan with mAdvance data (probably no longer available for new subscription now), and the Celcom First One 5 GB data plan.
In the table above, you will notice that the Internet data quota increases from plan to plan, starting from 2 GB to 5 GB. When you get more Internet data quota, you will at the same time have less voice and SMS quota as a trade off.
It seems that the new Celcom First Basic plan with OPTIMISER is pretty good if you use more data than voice/SMS, but occasionally might need to use more voice/SMS in a particular month.
Anyhow, the Celcom First One 5GB plan is still the cheapest one if don't make a lot of calls and send very few SMS. I think nowadays we use more Whatsapp, Line and WeChat rather than sending conventional SMS/MMS, don't we?
If you are existing Celcom First Prime subscriber with mAdvance data plan, you can make use of the table above to consider whether you need to switch over to the new Celcom First Basic plan with OPTIMISER, or to stay along with your existing plan.
