发明名称 Telephone comprising an identification module
摘要 A telephone is disclosed having a dummy removable SIM card which inhibits normal operation of the telephone while allowing turn-on of the telephone for demonstration purposes, as well as for memory back-up and restore purposes. The dummy removable SIM card authorizes operation of the telephone except for the transceiver, thus allowing a potential buyer to inspect the telephone features, such as seeing menus on the display, hearing tones, and cycling through different modes of the telephone. For compliance with telephone standards, such as the GSM standard, the dummy removable SIM card allows emergency calls which are typically free of charge and do not incur network connection charges.
