ABSTRACT:
A telecommunications system and method for allowing the owner of a Mobile Station to define usage limits based on air time usage or by a dollar amount, e.g., charging information. When the limits are exceeded, the Mobile Station will be inoperable except for emergency calls or calls to predefined numbers established by the subscriber. The accumulated usage (time/dollar amount) can be reset and the Mobile Station returned to normal operation by the subscriber using a user-defined password.
