WiFi Calling: Does not work without seeing the carrier service. The device works with cellular data turned off, but still within tower range, otherwise it will not work without it.

How can you be sure you are testing VoWiFi? From the sounds of it your are simply calling via your carrier's network. Turning off data has no impact on telephony. It only turns off mobile internet.

Ehartwork

@arubislander Yes. Just an observation. If I'm in area with no cellular service, I would think wifi calling should work without it. It doesn't work at all.

arubislander

@Ehartwork My point is, you are probably not testing VoWiFi at all, since that has not been reported to work on this device by regular users. One developer claims to have gotten it to work on a FP5, but this has not been independently verified.

The fact that what you think is WiFi calling doesn't work when there is no cellular service is a strong indication that WiFi calling is not available on this device.

Ehartwork

@arubislander Interesting. I will look into that. I appreciate you're input. Thanks.

I hope I'm not talking nonsense, but I think that VoWiFi, unlike VoLTE, just isn't working yet on Ubuntu Touch. Unless some changes have gone unnoticed (?)

Wifi Calling Availability
Device: Yes
Carrier (T-Mobile): Yes
Current OS Version (24.04-1.2): No

Note: My assumption that 4G LTE and wifi calling were synonymous is that the two technologies always seemed to be in the same discussions. I thought wifi calling was dependent on 4G LTE. However, this is not the case. Thanks to those who had taken the time to reply and help make me aware of this.

Due to lack of time, I asked Google. So, hopefully someone here will correct any errors:
Answer was: VoLTE & WiFi calling share some underlying code.
But VoLTE code more on modem & WiFi calling in OS.
Also, Halium 11, or newer . Better support with that (11) for WiFi Calling. (Nord N10 only on halium10).
I suggested (different thread) that WiFi Calling get added to all device pages, to make the distinction that VoLTE works on some devices, but WiFi calling does NOT, at present, on most UT devices. This would help prospective UT users decide on device.

Google also said that some developers said FP5 WiFi calling works sometimes, and this was due to different -newer- modem & firmware than most other phones.
I bought Nord N10 months ago, under same bad assumption: VoLTE (YES) & WiFi calling (NO) work. Wasted huge money & time. Had to buy active cell signal booster. (more $ than I paid for the phone).

BTW: No native RCS. (Just in case you expected that feature). Not listed, as far as I could tell, on devices pages.

@oldbutndy Google has not released control of RCS enough for us to do anything with it. There is a $10k+ bounty out for whomever first achieves it.

VoWiFi works by signaling over the VoLTE carrier channel to use the data channel (WiFi) for the voice part and not the carrier channel (audio can be sent via either channel). We need a button and a hook in halium to manually turn that on. There has been one report of a person who set that on in android and it remained after flashing UT. But that has not been confirmed by others. It could be it just does it without needing a button if it was already enabled, but we do not know.

@oldbutndy @oldbutndy I appreciate you taking the time to post your findings. I really like the OS, but before I can completely switch over I need the wifi calling option to work. Thanks again.

Ehartwork

@rocket2nfinity That's interesting. Thanks for the information.
