ABSTRACT:
An apparatus (100) and method (200) for enabling a wireless communication device operating in a locked mode to receive an incoming call is provided. The wireless communication device is equipped with a user removable module (118) containing user information. As the wireless communication device (100) in the locked mode initially transmits a call to an emergency service center (212), the wireless communication device (100) receives an indication allowing it to access some of the user information contained in the user removable module (216). Using the accessed user information, the wireless communication device (100) is registered in a local network (402), enabling the wireless communication device to receive incoming call for a predefined period of time (220).
