The wireless communication device is configured to self-adapt to various operating frequencies and communication protocols which may be present in the cellular communication environment so that the device is able to provide communications in several service areas even though the frequencies of operation and the communication protocols in use in the service areas may be incompatible with one another. <IMAGE>
