Abstract

See full text

A subscriber information storing module is fixedly and internally housed within a mobile station, which is provided with an interface which permits an IC card storing subscriber information to be loaded. When a power supply is turned on, if a module is not loaded into the interface, subscriber information in the internally housed module is used to perform an activation processing for the mobile station. When an IC card is loaded into the interface, an examination is made to see if the subscriber number of the IC card and the subscriber number of the mobile station coincide, and if they coincide, the internally housed module is disabled, and subscriber information of the IC card is used.
