An automated prepayment method for accessing wireless telecommunication services by a mobile terminal is disclosed. The method includes programming and storing in the mobile terminal subscriber credit information such as credit or debit card number, authorization PIN code, and the amount of prepayment credit to be bought. A registration request is sent containing a prepayment request indicator to the mobile switching center. The mobile switching center then requests that the mobile terminal transmit the programmed credit information. The credit information is sent to a prepayment clearing house to verify that the subscriber credit is satisfactory. If the response from the clearing house is positive then the mobile switching center grants the mobile terminal access to the network through standard registration procedures. On the other hand, if the subscriber's credit is not satisfactory then access to the network is denied and a corresponding message is displayed on the mobile terminal.
