To be able to make changes to the postpaid billing method, you must first have a prepaid billing account.
Your billing account can be switched to postpaid account through our admin.
If you have prepaid quota while your account is postpaid, API transaction usage will deduct your prepaid quota first.
The billing invoice for last month will be sent to your registered email address on the first day of the month (1st date). For example, the billing invoice which is sent on 1st August is the bill for usage on July (1st - 31st).
Please pay your billing invoice before 14th days after invoice sent, if the invoice is unpaid more than date 14th that date your account will be suspended on the 15th day.
