Postpaid mobile phone

The user in this situation is billed after the fact according to their use of mobile services at the end of each month.

Typically, the customer's contract specifies a limit or "allowance" of minutes, text messages etc., and the customer will be billed at a flat rate for any usage equal to or less than that allowance.

Theoretically, a user in this situation has no limit on use of mobile services and, as a consequence, unlimited credit.

In the US a smaller market has been captured by prepaid providers such as Boost Mobile, Metro by T-Mobile, Cricket Wireless, TracFone, and Ting, which use postpaid providers networks (e.g. Cricket runs on AT&T's network).

The alternative billing method is a prepaid mobile phone, where a user pays in advance for credit that is then consumed by use of the mobile phone service.This article related to telecommunications is a stub.
