Voice over WiFi (Vo-WiFi) is the one of the latest technology upgrade our smartphones got. It enables calling over Wi-Fi connectivity with more quality and efficiency. You can make a HD call through the Vo-WiFi without worrying about your cellular connectivity, all you need is better WiFi connectivity which is available around the world in almost every area. It's more beneficial for travellers or business class people who don't like to loose connectioans on the move.
Vo-Wifi enhances the quality of call and makes everything crisp and clear on the call.
Samsung has already pulled out this feature long ago. Now in OneUi 2 you can find option for Vo-WiFi in the quick panel and can even search it in settings.
