Question: What action does a UE (User Equipment) take when the Last RPLMN Selection Indication is set to '01' during switch-on or recovery from out-of-coverage, based on the USIM application settings?
Option 1: The UE attempts registration only on the HPLMN (Home Public Land Mobile Network).
Option 2: The UE skips the registration process on both HPLMN and last RPLMN.
Option 3: The UE attempts registration either on the HPLMN or the last RPLMN.
Option 4: The UE prioritizes registration on the last visited PLMN (Public Land Mobile Network) over HPLMN.
Explanation: This is because, with a Last RPLMN Selection Indication value of '01', the UE attempts registration either on the Home Public Land Mobile Network (HPLMN) or the last Registered PLMN (RPLMN) at switch-on or following recovery from lack of coverage, providing flexibility in network selection.
