The Jio sim started having problems since 3 weeks when the phone got updated. Then I changed the sim to slot 2. It worked for 2 weeks but now it's completely down. I tried replacing the sim but even the new sim is not being detected
My Jio 4g VoLTE sim is not getting detected and says unknown carrier. I inserted another Jio sim and it is working. Then I replaced my Jio sim but nothing has changed. The new Jio 4g sim too is also not getting detected. Please help me
