WiFi calling is the best solution for those who have poor reception at home and office. All smartphone manufacturers are competing to bring this Wi-Fi Calling on iPhone, Android, and other Mobile Platforms. As long as your calls are routing through the WiFi network no need to worry about network signal strength or call drops.
Once you enable WiFi Calling on Android or iPhone, then calls will route through Home or Office WiFi network. This feature utilizes your home or any other WiFi router as a mobile tower to connect the call and to route to the mobile tower.
The feature can be useful when you are on Mobile phone tower’s blindspot. You don’t need to worry about the availability of the tower signal. When you dial any number, your phone will automatically make calls using connected Wi-Fi instead of Mobile Phone Tower.
