Abstract
A mobile equipment (10), such as a cellular radio telephone, includes a controller (18) coupled to a wireless transceiver (14, 16) for bidirectionally communicating with one of a plurality of different networks (32, 32′), such as a GSM network and a Universal Mobile Telecommunications System (UMTS) network. A data storage module (28), referred to herein as a SIM/USIM or as a UICC (UMTS Integrated Circuit Card), is readably coupled to the controller. The module stores information for specifying at least an identification and the operational capabilities of the module in each of the plurality of different networks. The controller is responsive to a request received from one of the plurality of networks through the transceiver for accessing the module to retrieve the stored information and for transmitting the retrieved information to the requesting one of the networks through the transceiver.
