VoWiFi on Pixel7/Android14/SDK34

[090h]

After a long hesitant update of the phone firmware from UQ1A.231205.015/pims 1.2.4 to the most recent one VoWiFi stopped to work. Im out of luck in turning it working back. logcat suggest it fails at EAP for some unknown reason:

After a while i think it is somehow related to IMEI ([ IDr EAP Notify(41101) ]) . There are some shenanigans with IMEI in this country. Although i believe my IMEI is valid i have yet to see something like this in logs. Notice absence of break . As usual very "high" quality of google/android code.

[samuelgarabini]

Did you solve it? My VoLTE works, but VoWifi don't. I don't know if it is a problem with IMEI

About after updating to android 15 it worked for a brief moment.
Now it dont. Again! And the last thing I see in the logs is:
IkeSessionStateMachine: Received unknown or unexpected status notifications with notify type: 16385
Google reworked IKEv2/EAP in android 15. And again it is a buggy piece of crap. Though can confirm it works in android 13. Gough

How can you see the logs of the carrier? Can you help me? I want to try to find out what's my problem.
