I just discovered that Tenaga Nasional Berhad (TNB) has released a mobile app called myTNB for both Android and iOS smart mobile devices.
You need to register an account in order to use myTNB. After that, you can link all the electricity bills under your name to this myTNB account.
Then, you are able to check the billing status of each of the bills. This is particularly useful for residential property owners to check and ensure their tenants have paid for the electricity bill.
Beside that, you can also use myTNB to check for new electricity supply application status, Renewable Energy payment advice, report faulty street light, etc.
However, the report faulty street light is not done through the app itself, but still using traditional SMS method, which might cost you SMS charge for sending to 15454.
