Question: What is the prescribed method for closing an ISIM (IP Multimedia Services Identity Module) application after termination of its session?
Option 1: By shutting down the entire SIM card's power supply
Option 2: By closing the logical channels used to communicate with the ISIM application
Option 3: By restarting the mobile device (UE: User Equipment)
Option 4: By manually deleting the ISIM application from the SIM card
Explanation: Closing the logical channels specifically associated with the ISIM application is a targeted approach that isolates the closure to just the ISIM application, without unnecessarily affecting other applications or the entire SIM card. This method ensures efficient resource management and minimizes potential disruptions to other services on the UE (User Equipment).
