Abstract: A mobile communication device and method including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from an advanced network and a legacy network. The controller receives a message from the advanced network via the wireless transceiver for redirecting the mobile communication device from the advanced network to the legacy network in response to a request for a call, searches for a suitable cell in the legacy network via the wireless transceiver in response to receiving the message, and camps on the suitable cell for making the call via the wireless transceiver regardless of the suitable cell being of a low priority and whether there is another suitable cell of a normal priority or not.

Abstract: A method of selecting a SIM for a location service and a multi-SIM device utilizing the same are disclosed. The method, adopted by a multi-SIM device, includes: acquiring Secure User Plane Location (SUPL) information from a corresponding communications network which each SIM is in connection with; determining which communications network supports a location service based on the SUPL information; and requesting the location service on a SIM that is in connection with the supported communications network.
