Wi-Fi calling is a feature that allows you to make and receive phone calls using a Wi-Fi network instead of a cellular network. This is particularly useful in areas with weak cellular signal or no coverage, as well as when traveling internationally. With Wi-Fi calling, your device uses the internet connection to transmit calls, providing a reliable communication option even when traditional cellular signals are limited. It’s a convenient way to stay connected, especially in areas where cellular reception might be challenging. Users with iOS 17.4 and above can use Wi-Fi calling without any disruptions, for users with older operating systems, please update to the latest operating system to use Wi-Fi calling.
