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.
WiFi Calling Cost
WiFi calling is a free service and does not need any additional fees to your carrier. Most of the providers will count against your mobile phone plan minutes even though you are making calls through Wi-Fi.
But there are a few mobile plans (from T-Mobile and others) that let you make free Wi-Fi calls on a certain plan. If you are looking for alternate solutions to make absolutely free calls without counting your minutes, there are a couple of iOS app that you can get from iTunes.
