<p>A mobile communication device configured for Machine Type Communication (MTC) is provided. In the mobile communication device, a wireless module performs wireless transmissions and receptions to and from a service network, and a controller module starts a back-off timer in response to adding a Public Land Mobile Network (PLMN) identity to a forbidden PLMN list or in response to setting a subscriber identity card coupled to the mobile communication device as invalid. Also, the controller module further forbids any access to the service network via the wireless module until the back-off timer expires, and, before the back-off timer expires, stores an amount of a remaining time for the back-off timer to expire in response to a power-off of the mobile communication device or in response to detaching from the service network via the wireless module.</p> |
