New Redmi Sim K20 Pro 12.5.1 Sim card Suddenly not detected


Oct 6, 2021

Some weeks back my phone (Redmi K20 Pro) got updated. Before update I had an Indian sim card (Airtel) and a German sim card which were working perfectly. After the update the Indian airtel sim card is no longer detected in my phone. I have put the sim card in another phone and it works perfectly. Therefore there is no problem with the sim. I have checked for networks manually, have tried switching cards and have also tried a factory reset. The update to 12.5.1 has i guess caused this. If anyone has a solution to get my Indian card working pls share.

All the help is appreciated l,
