A mobile communication device. The mobile communication device comprises a radio transceiver to communicatively couple the mobile communication device to a radio access network by a wireless communication link, a memory, a processor, and an application stored in the memory. When executed by the processor, the application builds a communication history of the mobile communication device, analyzes the communication history of the mobile communication device to determine a pattern of communication usage of the mobile communication device, monitors recent communication usage of the mobile communication device, compares the recent communication usage of the mobile communication device to the pattern of communication usage of the mobile communication device, and when the recent communication usage of the mobile communication device differs from the pattern of communication usage of the mobile communication device by more than a predefined threshold, blocks at least one attempt to initiate communication by the mobile communication device.
