Do you know that Wi-Fi Calling on Samsung phones allows you to make and receive phone calls using a Wi-Fi network instead of relying solely on a cellular network. It helps you stay connected even if you have a weak cellular signal or no coverage. You can activate Wi-Fi Calling in your phone's settings, connect to a Wi-Fi network, and make calls as usual. It provides better coverage, clearer call quality, and can be beneficial for international calling. Wi-Fi Calling doesn't use your cellular data and can switch seamlessly between Wi-Fi and cellular networks during a call.
