Abstract: A method of selecting an active SIM for an emergency service and a multi-SIM device utilizing the same are disclosed. The method, adopted by the multi-SIM device, includes: receiving a request for an emergency call on a first SIM camping on an LTE network; determining whether a second SIM camps on a second communications network which supports an emergency service; and when the second communications network supports the emergency service, performing the emergency call from the second SIM.

Abstract: A communications apparatus includes a radio transceiver, a memory device and a processor. The radio transceiver transmits or receives wireless radio frequency signals to or from an air interface. The memory device stores a registration database including one or more sets of registration data. Each set of registration data corresponds to an International Mobile Subscriber Identity (IMSI). The processor determines whether performing a PLMN search procedure is required, and when performing a PLMN search procedure is required, the processor retrieves suitable registration data from the registration database according to a currently used IMSI and performs the PLMN search procedure via the radio transceiver based on the retrieved suitable registration data.

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.
