Hello all,

I am Indian, I recently moved to poland and phone was working fine with both sim (local poland) and Indian airtel sim. I received an software update recently after that my Indian sim is not been detected by phone.

Scenario 1: If both sim are inserted then network is not detected

Scenario 2: If only one sim is inserted (local poland) then works fine with network and data

Scenario 3: If only one sim is inserted (Indian) then Sim is not detected and no network

Thanks and regards,

Sopan B Uttarkar

Try your Indian sim in a different fully unlocked phone if you have access to one to eliminate whether its your sim card or your device. There's a chance your sim may have gone faulty.
