More Information
Summary:A multi-subscriber identification module (SIM) device is provided, and includes first and second SIMs, first and second radio frequency (RF) resources, and a baseband processor. The first and second SIMs are for using first and second services of first and second networks respectively. The first RF resource supports a non-limiting channel configuration use in accordance with a radio resource control (RRC) protocol. The second RF resource supports a limiting channel configuration use in accordance with the RRC protocol. The baseband processor, in a dual radio (DR) mode, configures one of the first and second SIMs as a main SIM based on information on the first and second networks, allots the first RF resource to the main SIM, configures the other one as a sub-SIM, and allots the second RF resource to the sub-SIM.
