What is VoWiFi?
VoWiFi is a Wi-Fi-based VoIP service. Where VoIP consists of the hardware and software that enables people to use the Internet as the transmission medium for telephone calls, VoWiFi is the wireless version of this technology which is designed to work on wireless devices such as Smartphones. The VoWiFi technology allows users to connect to a public WiFi hotspot or any standard private home WiFi network and make outgoing calls to any mobile phone number and landline, across operators, using handsets that support the technology.
