Question: In a SIM storing multiple MSISDN numbers, what is the display priority for MSISDN numbers during the mobile equipment's (ME) initialization procedure?
Option 1: All MSISDN numbers are displayed simultaneously without priority.
Option 2: The ME selects one randomly from the stored records for display.
Option 3: The last recorded MSISDN in the SIM is given display priority.
Option 4: The first recorded MSISDN in the SIM is displayed with priority.
Explanation: When a SIM contains multiple MSISDNs, the first recorded MSISDN in the SIM's memory is prioritized for display during the mobile device's startup. This ensures consistency and predictability in presenting primary contact information to the user, reflecting standard telecom practices where the first entry is often considered the primary identifier.
