Question: Under what access condition(s) can the Mobile Equipment (ME) perform an update procedure with Emergency Call Codes (EFECC) on a Subscriber Identity Module (SIM)?
Option 1: ALW (Always), CHV1 (PIN code 1), or CHV2 (PIN code 2)
Option 2: Only when ADM (Administrative Data Management) is set to CHV1 (PIN code 1)
Option 3: When ADM is set to either ALW (Always) or blocked, but not requiring PIN verification
Option 4: Only if the SIM card is in a specific, non-standard, emergency mode
Explanation: According to specifications for the SIM-ME interface regarding Emergency Call Codes, an update procedure can only be performed under certain access conditions. Specifically, these conditions are met when Administrative Data Management (ADM) for updates is set to Always (ALW), or if authentication via PIN code 1 (CHV1) or PIN code 2 (CHV2) is required, ensuring a balance between security and the necessity of updating emergency call information as needed.
