Thanks for being a part of Samsung community. We would like to like to inform that Wi-Fi calling allows you to use a Wi-Fi network to make and receive phone calls, rather than using the traditional mobile network. This benefits those in poor signal areas, such as rural villages and underground stations, as you'll be able to harness the power of available Wi-Fi networks to stay connected. Drop down notification panel>enable>Wi-Fi calling. Be sure to hit ♡ when you find an answer that works for you.
