Question: What is a prerequisite for the test scenario involving modification of the User Controlled PLMN (Public Land Mobile Network) selector list on a UE (User Equipment) with a USIM (Universal Subscriber Identity Module) application?
Option 1: Installation of SAT-NG-SS (Satellite Non-Gbps Speed Satellite) and a specific 4G-LTE UICC configuration.
Option 2: The default 5G-NR (5th Generation New Radio) UICC is used, with the UICC installed into the Terminal and the UE powered on.
Option 3: A manual update of the MCC/MNC (Mobile Country Code / Mobile Network Code) to a predefined value without powering on the UE.
Option 4: Utilization of an external SIM (Subscriber Identity Module) in place of the UICC for network authentication.
Explanation: This question assesses understanding of initial conditions necessary for specific telecom tests, particularly those involving USIM applications and PLMN modifications. The correct answer highlights the importance of using a default 5G-NR UICC configuration with the device properly set up (UICC installed and UE powered on) to ensure a controlled test environment, crucial for accurately testing network selection and authentication processes in modern telecom networks, especially when focusing on 5G capabilities.
