H1618667980868 , via OnePlus 9 , Jul 26, 2021 : Hi All, I have just updated my OnePlus 9 phone and after updated successfully, my SIM 1 network i.e. Jio India not connected. Only SIM2 network i.e. Airtel India is showing network. After checking to SIM Settings found that SIM 1 option is hidden for me. Only Sim 2 option showing i.e. Airtel. Tried all the possible ways but not working. Before update everything was normal, both network working fine. Please help asap.
