Question: What happens when a Mobile Equipment (ME) attempts to disable CHV1 (Card Holder Verification 1) for Service n°1, which is allocated and activated, but the presented CHV1 does not match the one stored in the SIM?
Option 1: The ME successfully disables CHV1 after a retry mechanism.
Option 2: The procedure ends unsuccessfully without altering the CHV1 status.
Option 3: The ME automatically enables CHV2 (Card Holder Verification 2) as a fallback.
Option 4: The SIM initiates a re-synchronization process with the network.
Explanation: According to the specified procedure for disabling CHV1, if the CHV1 presented by the ME does not match the one stored in the SIM, the procedure ends without successfully disabling CHV1. This ensures security by preventing unauthorized changes to the verification status.
