Abstract:
1. A wireless communication device comprising: a transceiver operable to communicate with a wireless carrier network and a wireless non-carrier network; a memory for storing at least a cellular phone number associated with the wireless carrier network and a WLAN phone number associated with the wireless non-carrier network, the cellular phone number and the WLAN phone number both being associated with calling one destination device; a controller, coupled to the transceiver and the memory, for determining whether the wireless communication device is within coverage of the wireless non-carrier network, and for causing only the WLAN phone number to be selected from the memory to call the destination device if the wireless communication device is within coverage of the wireless non-carrier network and for causing only the cellular phone number to be selected from the memory to call the destination wireless device if the wireless communication device is outside the coverage of the wireless non-carrier network; and a display coupled to the controller, the display for displaying one or more contact numbers in a contacts list with at least one of the WLAN phone number and the cellular phone number to a user, the displaying of said one or more contact numbers in a contacts list updated by the controller to display the one of the WLAN phone number and the cellular phone number, while at the same time not displaying the other phone number thereby preventing the user initiating a call to the destination device using the other phone number, when a call is being initiated by the user and the controller has determined a present coverage status of the wireless non-carrier network with respect to the wireless communication device.
