I've seen this issue on ROG Phone 6 as well, but why doesn't this device support TTA-VoLTE by default?
I hope it could be added as a feature in the future... currently because of this, this device has been unusable irl in here as the only VoLTE supported in this place is TTA-VoLTE
Tried almost everything, maybe qualcomm device manager or something I didn't try but that's not available in windows 11, so if it could be added in an update hopefully would be great as I'll be able to use this device finally after purchasing it.
