    Hello, Volte used to work well on my op9 pro recently updated to A12, I tied switching my sim card from sim 1 to sim 2 as I read some users were able to connect to 5g that way, well, it didn't work and when I switched my sim back, volte stopped working, tried restarting the phone a couple of times, no luck. Any ideas ?

    Is it only VoLTE that is affected or 5G vanished too?
    Have you reported it via the feedback tool?

    5g never worker for me in the first place, b but volte used to work after some tinkering in engineering mode and pdc, after A12 I'm not able to access engineering mode and fix volte, today volte stopped working suddenly.

    Then you didn't really have official support for it to begin with.
    Is it a officially supported region?

    Back when I got 7 Pro I had to complain on my carrier and Oneplus. Official VoLTE and VoWiFi support came on my carrier shortly after and has been supported since then.
