Abstract: A method and system for restricting at least partial usage of a wireless communication device 300, like a mobile telephone, includes a comparison of identification information 308 read from a user configuration module 307 with one or more restricted access identification codes. Where there is a match, some or all usage of the wireless communication 300 device is restricted. A usage restriction module 309 then compares the identification information 308 with one or more restricted access identification codes, which identify one or more networks associated with service providers with which usage of the wireless communication device is restricted. Where there is a match, at least partial use of the wireless communication device 300 is restricted.
