Question: Under what condition may a Mobile Equipment (ME) optionally deactivate the Universal Integrated Circuit Card (UICC) after entering Power Saving Mode (PSM) to reduce power consumption?
Option 1: When the UICC is not provisioned with any subscription profile.
Option 2: When the ME is in an area with limited network coverage.
Option 3: Only if the Personal Identification Number (PIN) of the Universal Subscriber Identity Module (USIM) is disabled.
Option 4: Immediately after every PSM cycle to optimize battery life.
Explanation: This condition allows UICC deactivation in Power Saving Mode (PSM) only if the USIM's PIN is disabled, ensuring security measures (PIN verification) aren't bypassed for power-saving convenience.
