How to enable VoWiFi on mobile - Dialog launched first VoWiFi calling in Sri Lanka
WiFi calls (VoWiFi - Voice over Wireless LAN) use a wireless network to make a call or send a message instead of sending it over the cellular network. This can be very useful when you are on the edge of a mobile network and the reception is bad. It also works very well if you are in a building that can prevent the signal from entering, especially in the basement. This technology allows users to make and receive calls over WiFi without having to connect to a mobile network. Calls are made using the standard dialer without using any additional application. You can get full explanations and how to use this technology on the video above.
