Does Fairphone 4 supports VoLTE ?

adorsaz

Hello,

I'm using Ubuntu Touch since January on my Fairphone 4.

Some days ago my phone service provider emailed me an annoucement about the near shutdown of 3G network. They provided me the information that I have to use VoLTE to be able to continue to make and receive calls.

My provider is Yallo in Switzerland and it uses the Sunrise network. Sunrise will shutdown the 3G network next June.

My question is: should the VoLTE option work with Fairphone 4 ?

The device information here say no, but it seems some recent developments happend on VoLTE.

I see a switch on Ubuntu Touch setting to enable the VoLTE but it seems disabled. Is there some thing to do to enable it like using stock Fairphone OS ?

Edit: I'm runnning the Ubuntu Touch stable channel (focal OTA 8). I've let default phone provider access point configuration (only "internet" is enabled, no MMS neither LTE). My phone is connected with LTE already.

@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.

@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 ?
