VoWifi on TMobile NL ?

[marcel112]

Guys,


I am using 10 Pro global.

I can use vowifi on mi9 on Tele2(sub brand tmobileNL) but can't get it working on my sim from TMobile...
TMobile USA also supports vowifi on mi10 Pro.

I have the option in menu activated but still doesn't work... Who can help me?
I am running Xiaomi genuine stable build 12.0.1 global
