Hey Guys,
many people got VOLTE and VOWIFI activated on Pocophone, OnePlus and Mi8 by editing the Profile of Modem with Qualcomm PDC tool.
here is the tutorial for OP6 / 6T
I try to connect with MIA1 but no chance to get connected with 8.1 and 9.0 Roms
maybe one way is edit a Modemfile with correct Profile ????

However, it is recommended to use the "H3G_Denmark_Commercial" Profile, as it has no restrictions.
1. Enter *#800# and select "oneplus Logkit" --> "Function Switch" --> "VoLTE switch", "VoWiFi switch" and "VT switch".
If "VoLTE switch", "VoWiFi switch" and "VT switch" are not present, then install this APK "OEMLogKit.apk" and restarts!
Now "VoLTE switch", "VoWiFi switch" and "VT switch" should be available under *#800#!
2. After you have selected "VoLTE switch", "VoWiFi switch" and "VT switch", restart the device,
and in the "Settings" under "SIM & Network" select "VoLTE and WiFi-Calling".
3. Go to your computer and install both.
