Claim 15:
16. A non-transitory computer-readable medium storing instructions that, when executed by processing circuitry, cause the processing circuitry to perform a method for selecting a Public Land Mobile Network (PLMN) in a wireless communication system by a User Equipment (UE), the method comprising:
detecting, by the UE, that the UE is operating in an interworking mode based on a usage of a SIM card;
triggering, by the UE, a manual scan in the interworking mode for acquiring a list of PLMNs in the wireless communication system;
causing, by the UE, a display to output the list of PLMNs in response to the triggering
receiving, by the UE, a first selection of at least one PLMN among the list of PLMNs from an external source or a second selection of a selected network class from the external source;
registering the UE with a selected PLMN among the list of PLMNs based on the first selection or the second selection.
