Question: When a UE (User Equipment) is selecting a network to register on, which of the following lists takes precedence over the Operator Controlled PLMN (Public Land Mobile Network) selector list?
Option 1: Automatically Generated PLMN selector list
Option 2: User Controlled PLMN selector list
Option 3: Default PLMN selector list stored on the ME (Mobile Equipment)
Option 4: Last Used PLMN selector list
Explanation: The correct answer is Option 2 because, according to telecom network registration protocols, a User Controlled PLMN selector list allows subscribers to prioritize networks based on personal preference, which typically takes precedence over Operator Controlled lists to ensure user choice is respected when multiple viable networks are available. This aligns with principles of user-centric network selection in mobile telecommunications.
