I recently received an email from T-Mobile telling me one of my devices does not have VoLTE enabled. The phone number referenced (using only the last four digits) points to my daily driver, a Moto G5 Plus running LOS 14.1 Unofficial (a 2022 build).
They say that things may not work well after June 2022.
Though VoLTE is provisioned, IMS status shows unregistered and all services unavailable. Bummer. There are no VoLTE specific settings in the Nougat ROM. I multiboot on that device. I may have to check each ROM to see what their status is.
Also don’t know if the SIM is a factor. In use since at least 2013/2014, mostly in my beloved LG G3. Hate to think I’d have to give up my comfort zone and install a more modern Android just to keep it working ( I really dislike modern Android - Q/R/S/whatever).
Gonna have to start rethinking a lot of things. grumble.
hazy memories… where is ims_user_agent read out from? if it’s from a firmware file or some carrier config, maybe if you lie about the user-agent ims-registration goes thru, it’s still SIP - but could be tied to IMEI still as that t-mobile check implies. Incompatibilities ofc can stem from not supporting an audio codec , lte-bands etc. Phone numbers are still held hostage
Under IMS Status;
IMS registration : Not Registered
the other are all; Unavailable
Is this my problem? I have no 4G calling only 3G or H+. Yet the VoLTE is provisioned.
Here is the most interesting thing to me, when I make a Signal Messenger calls LTE calling works, just not voice calls.
How do I get IMS working? This is a OnePluse Nord we are talking about.
These two things are actually different. Signal calls are simply carried over the data connection, (even at less than 3G speeds). VoLTE is a separate, specialized technology.
Thank for the link. I called my provider and they said they provisioned my OnePlus or at least that said that.
Apparently there are proprietary libraries needed to get the VoLTE working. I would think the 5G data would still work. I notice they have not update the Nord to e 1.1 yet I think someone was looking at it (5G).
I have bought 3 Samsung Galaxy S7’s and 1 S9. I am using them i Europe wit KPN provider. E/OS does not have the VoLTE option so I am falling back to 2 G which will be shut down this summer.
Is there a solution or better sell the phones after roll back to stock android if that is still possible.
Hai Rob, Are you from Holland?
Maybe you can help me out?

Eosfan,
Hi, I am in the US. And I am using a sm- g965f.
I thought I was going to have the same problem when 3G was turned off here. I even got a VoIP number and installed Cheogram to use it on this handset when mine quit working. That was almost 2 years ago.
Mine still works fine. When I am on a call my signal status say it drops to 3G and I sometimes have problems connecting back to data after a call. A quick restart fixes it every time so far.
I read that because this phone was originally Volte it is still working as such, it is just not displayed by the operating system.
I used the windows easy installer and still get monthly system updates from e and they have updated my handset to android 11. Starting my third year on the first. I love my e phone.

Thank you very much Robert for explaining. Okay so it keeps working although there is no VoLTE option in E/OS. The technicians at my provider say it is switching back to 2G. Very confusing this is. I do have a bad signal after 10-15 minutes in every call I make. There is no option or switch inside E/OS to use VoLTE is there?
There can be, depending on your phone, your mobile network provider and possibly your plan with them.
I have a VoLTE switch in my SIM card settings on a Fairphone 3 (Telekom Germany SIM card). I used to have it enabled without any obvious issues, but right now I have it disabled for testing purposes.
