Here, you can take a look at your plan’s current balance, remaining minutes for calls, messages, remaining data, as well as your purchased subscriptions. That way, you can always make sure you’re updated and won’t go beyond your plan’s limits.

You can also pay and verify your bills through this app so are assured that you’re paying directly to the biller. If you need additional packages, you can also make your purchase within the app. Some of the available packages include internet data, SMS, calls, and more.
