Hi. I have two days interesting problem. When i have setting in SIM Card set to Prefer 4G network i got no signal message when i want make some call. 4G internet on card is working but no signal for calling. When i set prefer 2G network in setting than signal for calling is OK without problem. Can this be a hardware problem ? Before my calling on 4G working ok in this location and i dont change any other settings.

I am on MIUI Global 12.0.4

thx
