Prepayment
Check your prepayment balance and deduction history.
Select the profile icon in the upper right of the home screen, then select the My usage menu. In the left menu, select Balance.
If you have a prepayment balance, it is deducted from the billed amount first. You can also review the amounts you have paid, the payment status, and the balance deduction history.
For records through last month, see Billing and Payment History. For this month's estimated charges, see Invoice Preview.
