Question: In a UICC with multiple USIM Applications, what is possible when there are different configurations of SUPI types (at least one IMSI-based and one non-IMSI-based USIM)?
Option 1: Only the IMSI-based USIM can be selected for use.
Option 2: The selection of a non-IMSI based USIM will automatically deselect any IMSI-based USIM.
Option 3: The UICC must prioritize the selection of an IMSI-based USIM over a non-IMSI based USIM.
Option 4: A non-IMSI based USIM can be selected in parallel with an IMSI-based USIM.
Explanation: This is correct because, when a UICC has multiple USIM Applications with different SUPI types (including at least one of each), the system allows for the concurrent selection of both a non-IMSI based USIM and an IMSI-based USIM, enabling flexible operation modes catering to various network and service requirements.
