ABSTRACT:
A method and apparatus for changing the mobile identification number of a cellular telephone unit to reflect a local network planning area number, including a cellular telephone unit having a microprocessor and associated data storage. The microprocessor is programmed to interrogate the cellular telephone unit to obtain the local system identification number. The network planning area number corresponding to the system identification number is included as a part of the mobile identification number such that the cellular telephone unit appears as a local unit to enable calls to be pre-validated by the local cellular system.
