Working VoLTE reports, share your experience
-
I've upgraded my vollaphone 22 to 24.04-1.1 and enabled voLTE, for now everything seems to work as expected with "free mobile" (french provider). The phone stays in LTE while I call, and i can browse the web.
If I see any bug I will get back to you!

Never mind, it seemed to have been a temporary issue thankfully, hopefully it won't bother anyone!
The experience I had from it and a possible 'solution' (if that's a reasonable term for it) can be found here: https://forums.ubports.com/post/91229

I just got over 250MB a second on the NORD n10 5g with VOLTE ive been hearing news about shutdown of 4g on t-mobile starting next month and only certain 4g devices will run the question would be since I am getting 250 sometimes 500mb would that be stand along 5g and the only reason I am asking is iver heard reports oneplus didnt enable sa in the x51 firmware but feels like im getting standalone speeds I just hope this phone continues to work after the phase out of 4g how much speed do we need LOL!!

If this is not planned obsolescence I don't know what it is.
While in France we still have at least on solid year before 2G disappears, and 3-4 years before 3G disappears!

hallo Forum,
I have a volla x23 phone with 24.04-01 stable and my experience with VoLTE is not so good.
Calling with VoLTE is difficult. There is no dial tone and you don't know if the call will go out at all or if the destination is busy or no one picks up.
I have disabled VoLTE again!
many greetings

@Charly same on Volla Quintus with 24.04.1.1 stable on it.

hi,
I have a
Fairphone 4
UT 24.04 1.1
Germany
Fonic (Telefonica, O2)overall its working pretty good. I have a more stable phone call connection with better quality because before the last update only 2G worked for me.
a nice additional benefit for me is the gain in battery life while staying on 4G all day long
VoLTE was disabled as I switched to 2G only and went back to 4G. After restarting the phone VoLTE was back there again.

I just discovered that I missed this. I'm with my POCO X3 NFC on Focal, dev channel and VoLTE work like a charm with my carrier... and it lows the consumption of battery.
Thanks for the work! -
Voxi also works
-
Any updates or thoughts on the best device for VoLTE in US on T-mobile? I ordered a Fairphone 4 but the order was canceled (I guess the seller doesn't actually ship to the US) so now I'm wondering if I'm better off going with a different device anyways?

@majorquibble OP N10 is confirmed to work with VoLTE on both T-Mobile and AT&T on the 24.04 daily builds . The same porter has activated VoLTE on the OP N100, but not confirmed yet by US users (I'll be testing it myself very soon).
-
@rocket2nfinity wow looks like used OP N10 goes for pretty cheap on eBay! Thanks!

OP N10 in US on AT&T MVNO. VoLTE working very nicely.
Setting context to dual protocol, I can also confirm 5G works on NSA towers! Getting 90-120mbps download, with no VoLTE issues (still able to send/receive calls with NR data channel).
