Abstract: A method and system for connecting a user identification module to a wireless host device are described. The user identification module is inserted in an accessory card that fits in the host device, and includes a radio transreceiver to connect to a wireless network. When the accessory card is placed in the host device, a mating surface of the host device blocks removal of the user identification module from the accessory card. The accessory card may be connected to the host device by inserting in a slot of the host device an edge of the accessory card from which extends an interface.

Abstract: A wireless personal mobile terminal in a cellular data network includes a packet radio transceiver for communicating with cellular base stations and a paging receiver for receiving paging signals from a paging transmitter serving a large geographical area. The wireless personal mobile message unit has power-saving features built into the signal format. This personal mobile message unit accommodates many communication applications due to the high bandwidth and the low latency achieved in the cellular data network. Low-power operation and wide coverage is achieved using existing one-way paging infrastructure. The wireless personal mobile unit can be achieved inexpensively by modifying a conventional one-way pager.
