Question: During IMS operation initialization on a Terminal with a UICC, what happens after successful selection of an ISIM application using the SELECT by DF name method?
Option 1: The Terminal proceeds directly to IMS service activation without storing any selection data on the UICC.
Option 2: The selected ISIM (AID) is temporarily stored in the Terminal's memory for the current session only.
Option 3: The selected ISIM (AID) is stored on the UICC, making it available even after UICC deactivation followed by reactivation.
Option 4: The UICC automatically selects an alternative application if the initially selected ISIM application is not available.
Explanation: This is correct because, after a successful ISIM application selection using the SELECT by DF name method, the selected ISIM (AID) is stored on the UICC. This ensures that the last selected ISIM application remains available even after the UICC undergoes a cycle of deactivation followed by activation, providing continuity for IMS operations.
