Question: During a call, if the Mobile Equipment (ME) sends a STATUS command to the SIM as part of proactive polling and receives no response data, what action must the ME take within a specified timeframe?
Option 1: Retry the STATUS command up to 3 times before taking any further action.
Option 2: Terminate the call as soon as possible but at least within 5 seconds after the STATUS command has been sent.
Option 3: Alert the user of potential SIM issues via a notification on the device's display.
Option 4: Automatically switch to an alternative network if available.
Explanation: This is because, according to the specified behavior for proactive polling during a call, if no response data is received to a STATUS command, the call must be terminated swiftly (as soon as possible but at least within 5 seconds) to ensure the integrity of the session and detect potential SIM removal or issues.
