No VoLTE and VoWiFi on Yallo (Sunrise) in Switzerland

free23

The code is star#star#4636#star#star (wouldn't let me post the symbol for star so I had to write it out) and yes it seems a few of us having problems with Wi-Fi calling on Pixel 7 specifically. Works no problem on stock Android but not working on GrapheneOS

Thank you. It look like everything is Ok and VoLTE and VoWiFi are switched on.

pampur Can you tell me where I can find the VoLTE setting? I can't find it in my preferences. I know that it's activated from my provider.

Yep same here

pampur Please take a moment to go and add a comment to the issue that I have raised on GitHub, hopefully the more people that comment the quicker this will get addressed: https://github.com/GrapheneOS/os-issue-tracker/issues/1648

It should be between, "Datenwarnung und -limit" and "Bevorzugter Netztyp"
But unfortunately on your device it's not displayed, your screenshot shows that.
That's really strange.
