I upgraded to S7 and want to give old Verizon S4 to family member to make / receive calls on wifi only. I don't see the appropriate options in Settings. Specific directions would be MUCH appreciated.
Welcome to Android Central! Also, if you have some kind of landline service (like Comcast/Xfinity), check to see if they have an app that will allow you to make calls over wi-fi. Xfinity Connect allows the user to make and receive wi-fi calls that originate from the landline.
