Since our provider is switching off 3G, I need to switch on VoLTE in my Sony Xperia III. In the Settings “Mobile Network”, I try to toggle the switch “4G calling (VoLTE)”. It starts to pulse on and off, but keeps being “Not registered”.
Has anyone had a similiar issue? I run on sailfish Pispala.
Please use the forum search.
It could be the same problem as here: [10 III][VoLTE] modem_auto_config.service fails to start
Thank you for the links. I have to admit I don’t understand how I can find out what to actually do. It seems a hard problem and mainly a question of being lucky or not. I hope this won’t mean the end of sailfish for our three devices.
does you sim support VoLTE?
I think yes, although I could maybe ask someone with a different phone to check it. It is from 2024.
It started blinking for me also on Jolla Phone 2026. Then I rebooted my phone and the setting stayed and the service was registered.
ofono-vendor-qti-radio-plugin package should take care of that. works for me (and afaict it should be available for xperia iii)
this hasn’t happened for me here.
Ah, ok – is there documentation where I could learn how to get and deploy this package?
FWIW VoLTE “should just work” on Xperia 10 III. It does here.
