Question: What conditions must be met for a Mobile Equipment (ME) to optionally deactivate the UICC after entering MICO mode, when the UICC does not support the UICC suspension mechanism?
Option 1: The ME must have an active BIP session, and the PIN of the USIM is enabled.
Option 2: The UICC does not support the UICC suspension mechanism, and only if the PIN of the USIM is disabled.
Option 3: The ME has successfully resumed a previously suspended UICC, and any proactive UICC session is terminated.
Option 4: The UE is in an active call state, and the ME has verified the content of EFICCID.
Explanation: This option is correct because if the UICC does not support the UICC suspension mechanism, the ME may optionally deactivate the UICC after entering MICO only if the PIN of the USIM is disabled, ensuring security measures (PIN protection) are not bypassed during power-saving modes.
