What is Vo-WiFi or Wi-Fi Calling ?


We all have suffered call drops and network congestions when calling in basement or with poor signal. Vo-WiFi is here to solve these issues.

Wi-Fi Calling is a High Definition (HD) voice service that uses a High Speed Internet connection to let you make and receive calls over a Wi-Fi network.

In simple words, it enables users to use smartphones that support Vo-WiFi to dial numbers to use voice when a Wi-Fi connection is available. Users can make outgoing calls even where there is poor cellular connectivity and is designed to address problems of insufficient coverage, especially indoors. So, the VoWiFi enabled SIM is required but it uses the Wi-Fi network to actually make the calls.
