Extension of coverage: The main advantage is when you are in an area where your mobile phone operator has a weak or non-existent GSM signal.

The function is also recommended in the homes in the cities, where the walls of the concrete buildings prevent the GSM signal received from the mobile phone operator.

During the connection to Wi-Fi calls, the iPhone may not receive emergency alerts.
