ABSTRACT:
A method facilitates provisioning of pre paid wireless services. Credit refresh operations involving a pre paid wireless communication device involve SMS messages transmitted to the device over the air. The device uses tariff tables to keep track of a call's impact on available credit. The tariff tables are updatable at the service provider's discretion using SMS messages.
