Thanks for being with Samsung and for sharing your query. We would like to inform you 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.
