5G yes, VoLTE and VoWiFi no (Swisscom)

Honor P90, Huawei Mate20: voLTE does not work with Yallo and many others! Hands off! Honor and Huawei are - for whatever reason - hardly supported by any mobile provider. These phones are no longer functional after switching off the 3G network.

It is possible to unblock WO-WIFI and VOLTE by following a tutorial on Google ;) (at least I did).

Est-ce que quelqu'un a essayé de débloquer le VOWIFI et le VOLTE comme renseigné sur certain forum (utiliser google), car apparemment on pourrait le débloquer sur le telephone. Je ne peux pas poster de lien car digitec me censure.

Has anyone tried to unblock the VOWIFI and VOLTE as reported on some forums (google it), because apparently it could be unblocked on the phone. I can't post a link because digitec censors me.

5G yes, VoLTE and VoWiFi no (Salt).
And I have almost no reception at home.
Huawei P30 also worked with Salt. So it will not work with the device. Galaxus. This information must be included in the device description.

5G with Sunrise is running. Unfortunately, VoWifi does not work because Sunrise does not have good mobiles on its list. It did work with Sunrise for the Huawei P30 pro. They only promote Apple and Samsung. But diversity is unknown at Sunrise
