My mobile network is Vodafone. The minute I have my simcard in my redmi 9 pro whoever calls me shows up as unknown. I also tried to insert the SIM card into my wife's Xiaomi phone and same problem occurs. But if I put her simcard (Vodafone also) and other Vodafone SIM cards the problem is gone... I've tried to call Vodafone but they have no clue what's going on.... They are trying to tell me the problem is within my phone...
