Question- How does Wifi calling shifts between data and wifi services?

Solution- When you have an active Wifi calling option in your smartphone then you can call normally from your network and when your signal becomes weak it will transfer the call to wifi services without any interruption.

Final Verdict

VoWifi is no doubt a great function for people who have bad network problems in their area. But still, I will say there are many problems while using Wifi as a calling option as we discussed interference and other problems but in the future, it will be a great feature.
