Is VOLTE not working anymore? My wife’s works on T-Mobile. R sim 12 plus. But I cannot not get voice over LTE to work. Everything else works

But going forward I cannot unlock any phones with rsim 13.

Any chance you've further updated to 12.4 and still have rsim13 unlock preserved? I'm still on 12.1.2 because of jailbreak, but now that there's support for 12.4, I'd like to make the jump if I can keep the unlock.

Same question:

If you're already unlocked using RSIM 13, can you take the 12.4 OTA update and remain unlocked?
