ABSTRACT:
A system is provided for prepaid handset credit activation. The system includes a prepaid handset, a subscriber identity module, and a server. The prepaid handset is associated with a prepaid handset identifier. The subscriber identity module is associated with a subscriber identity module identifier. The server communicates with a communication device to receive the prepaid handset identifier and the subscriber identity module identifier and determines whether both of the prepaid handset identifier and the subscriber identity module identifier are associated with prior activation. The server also applies credit to account information associated with the prepaid handset in response to a determination that both of the prepaid handset identifier and the subscriber identity module identifier are not associated with the prior activation, and activates the prepaid handset for user communication in response to applying credit to the account information associated with the prepaid handset.
