Does Fairphone 4 supports VoLTE ?

stanwood

@adorsaz The Fairphone 4 fully supports VoLTE and VoWiFi.
The latest news is that VoLTE will be available on Fairphone 4 with Ubuntu Touch as soon as we update to Noble.
So hopefully within the next few months.

P.S Happy to see another Swiss user here

@stanwood and @adorsaz
It might already be available in Devel.
But I don't have this device to check things out.

@AppLee No not yet Marius was working on it.

@stanwood I also live in Switzerland
I've got Fairphone 4 running 24.04-1.0 Beta 2 and my carrier is Yallo.

4G VoLTE is turned on but is unfortunately not working.

In the Ubuntu Touch Docs ( https://docs.ubports.com/en/latest/userguide/dailyuse/volte.html) one of the requrements is „Ubuntu Touch contains a VoLTE configuration for your carrier.„

Does anybody know how to create such a configuration?

I haven't seen it documented anywhere( or I'm blind ) but it looks like VoLTE was backported(?) to 20.04-OTA10. I did one call so far and did not see the "3g" downgrade in the status bar. And the cellular settings newly offer "Connection Type: 2G/3G/4G/5G"

@Ben-LinuxMan My provider is Yallo too and the VoLTE is working on my LineageOS installation with the Fairphone 4.

For your information, I share below screenshots of the current Android APN confugurations. Maybe that could help you to set up VoLTE on Ubuntu Touch ?

With the Ububtu Touch noble just released, I'll try to install it again in next days and I'll write here if VoLTE works for me.

@adorsaz
VoLTE is for Voice over LTE.
Sadly it has nothing to do with data or SMS and MMS setup.
4G (and 5G I believe) data works perfectly under Ubuntu Touch, same goes for SMS and MMS.

Sorry for the idle question, but I have seen on this forum a post complaining that Volte was working yes, but there was no feedback for the call routing, in a word, the user was launching the call, waiting in a void, then suddently hearing the voice of the called person. It was not on a Fairphone, it was with a Volla 23 IIRC, but is this a generic problem with current Volte and Ubuntu Touch ?

@gpatel-fr

I just made a call, I got the standard ringing until the other side picked up the phone

~~Though again, I'm not sure if the lack of a "3g" icon is proof enough that volte is actually working~~ Cellular Settings -> Carrier & APN -> 4G calling (VoLTE) is available and enabled
