A method and system for restricting at least partial usage of a wireless communication device (), like a mobile telephone, includes attempting to establish a communication channel () across a data network, such as non-IMS VoIP communication channel over a wide area network () like the Internet. Where the device () has been subsidized by a voice over data protocol service provider (), the method permits such communication only when data communication channels having service provider identifiers () corresponding to one or more permitted data access identification codes () are accessible. Where they are not, at least partial usage of the device () will be restricted.

Method and apparatus for providing a data protocol voice enabled subscription lock for a wireless communication device

The invention provides an apparatus and method for service access for a mobile communication device. The apparatus can include an identity module for storing user information in the mobile communication device. The identity module can include an identity module frame, a secure storage memory coupled to the frame, the secure storage memory including a mobile communication device subscriber identity and the user information, and an identity module controller coupled to the secure storage memory and the frame, the identity module controller configured to block access to the user information and grant access to the mobile communication device subscriber identity when the identity module enters a blocked mode. The identity module controller may grant access to the mobile communication device subscriber identity in response to a request for a service access communication.

Method and apparatus for operating a blocked secure storage memory

An apparatus and method for updating a subscriber identity in a mobile communication device. The apparatus can include a subscriber module, a memory configured to store the subscriber identity, a transceiver configured to receive a new subscriber identity from a wireless network, and a controller coupled to the memory, the transceiver, and the subscriber module. The controller can be configured to control operations of the mobile communication device. The controller can also be configured to re-personalize the mobile communication device to the new subscriber identity.
