Basically one day all of a sudden I lost all mobile network, can’t receive SMS, calls, etc, can’t use mobile data, nothing.

I own a Xiaomi Redmi 12 OS version 1.0.7.0.UMXMIXM Android version 14 UP1A.231005.007

I’ve tried going into the setting mobile network and disabling automatic connection and trying to connect manually but it doesn’t let me connect
