Question: What happens to an ongoing non-emergency call when the UICC (Universal Integrated Circuit Card) containing the active USIM (Universal Subscriber Identity Module) is removed from a mobile terminal supporting multiple UICCs?
Option 1: The call is put on hold until another UICC with a valid USIM is inserted.
Option 2: The call is automatically transferred to a secondary active USIM if available on another UICC.
Option 3: The call continues uninterrupted, using cached subscriber data.
Option 4: The call is terminated immediately.
Explanation: Removing the active UICC during a non-emergency call disrupts the connection, leading to immediate termination. This ensures security and prevents unauthorized access or billing discrepancies.
