VoWIFI not working on Poco X3 NFC

[amnher]

Has anyone able to make VoWIFI work in their respective countries? cause mine VoLTE is the only one that works. If I transfer my sim to another capable phone... it works.
So it is an issue with my Poco X3 NFC... I saw a thread here https://xiaomi.eu/community/threads/activation-of-volte-and-vowifi-in-xiaomi-eu-rom.63469/
has anyone tried? and does it retain even if I flash stock rom again? cause I remember fixing a redmi 3x before wherein I enabled some bands for LTE and it retains to whatever rom I install

Hello. I am new in here but have the same problem. Any news @amnher @TomSak ?
I did not try the link because I keep the factory rom. That one does not allow some of the procedures. Is it different in that issue? Am I wrong in finding the Vowifi not working in the phone - Poco X3 NFC
I don't have an easy contact to the support team in here.
