I would like to put something right, we have a Magic 5 Pro and a 6 Pro at home and Volte works on both mobiles (we have Sunrise) On the 5 Pro I can no longer switch off Volte after the update to Android, it stays on, on the 6 Pro you can choose yourself.

I can indeed report positive things. I ordered the Magic 6 pro for testing. Volte works perfectly out of the box. I also got Vowifi to work with a workaround.

So no recommendation to buy, sunrise and Swisscom will switch off the 3g network next year.

With the same. Honor is not officially represented here, so VoWifi and VoLTE are not possible
