1. A method of operating a wireless communication device including first and second subscriber identity modules (SIMs) to access a packet switched (PS) network including an Internet packet data network and an Internet Protocol multimedia subsystem (IMS) packet data network, the method comprising:
configuring the wireless communication device to utilize the first SIM to access the Internet packet data network based on a preference of a user among the first and second SIMs; and
configuring the wireless communication device to utilize the first SIM to access the Internet Protocol multimedia subsystem (IMS) packet data network for performing first type call, when a first operator corresponding to the first SIM does not support a circuit switched (CS) network for performing second type call.
