Wi-Fi Calling Explained in Detail

Wi-Fi calling is a game-changer for anyone with spotty cellular coverage. It allows you to make voice calls over a Wi-Fi network, eliminating dropped calls and poor sound quality.

Wi-Fi calling uses your internet connection to make calls, rather than traditional cellular signals. This means you can make calls from anywhere with a stable internet connection, even if you don't have a strong cell signal.

Wi-Fi calling is available on many smartphones, including those from top brands like Apple and Samsung.
