I am using OnePlus3. In my cellular network setting, I don't even have option to enable VoLTE. As for wifi calling, when I enable the wifi calling, wifi is automatically turned off right after I enable it. Anyone know how to set up Volte and wifi calling on Oneplus3? I asked tech support and they said they don't know why. Thank you

My guess is that since this post was 2016 and it is now 2020 they have not lost enough customers to warrent allowing those to bring their own phones access to wi-fi calling. No idea why not as you are still paying for the sevice but what good is the service if you do not get reception....
