Found this posted on another site. Looks like this could help for anyone with issues on these Samsung phones (USA, Exynos).
"I have confirmed these applications will allow you to use VoIP via your LTE connection as a bandaid till VoLTE is released. Both can be found in Aurora and are a “quick fix”. If someone is on T-Mobile the “DIGITS” app is included with their subscription already at no additional cost. With the magicApp you can buy the hardware for home VoIP & a 12 month subscription for the same price as just the app via G*#gle Play(for 12months) and not have to login to the Gapp store or give them a commission. My advice is to buy direct if going this route, not via GPlay store.
For non-FOSS apps having only 1 or 2 trackers was surprising to me. We know how to block these if they are “non-essential” obviously. The permissions… Another story but these apps are managing calls and SMS/MMS so a bit more understandable.
With many mobile companies turning off 2G and 3G to free up spectrum is VoLTE for Samsung in works? Seems to me the phones will become very bad without this.
Well, I thought it was working off VoLTE as my provider in America emailed me that VoLTE or 5G will be needed this year for phone calls. I am running iode’ 2.4 on a Sony Xperia XZ3 and have VoLTE enabled in the settings here:
VoWifi is also not working on the FP3 (Germany Telefónica) with latest Iode 2.4 build. IMS is registered however VoWifi not available, although turned on in the settings. I switched from FPOS where it worked
Its enabled and greyed out for me as well and working (was the same with stock ROM). What does IMS service say (see three dots)? You can do a test call and see if mobile data remain at 4G.
I am resuming this old post, since I would like to understand if all the issues with VoWifi and VoLTE are sorted out, for the phones sold by iodé.
I would like to buy one to try iodé OS (while waiting for a tablet ), but I will not without those features… I read that, in the past, Samsung devices were not enabled… since I am looking for a Note 10+ or a Note 9, I would like to know that before purchasing.
VoWIFI / VoLTE is unfortunately not available on Samsung devices sold by iodé…
We are soon updating the website and will provide this information on each product page.
Are there any updates on using Fairphone 4 with Vodafone and Wifi-Calling? Last time I used iode-OS it didn’t work, and that’s a dealbreaker for me, although I would really like to switch back…
