I have only one sim jio postpaid in my s21 fe.But some weird network issue plagued my phone. Network bars showing full but there is no network sometimes...no internet connection,cant make call if others call at that time ,its saying busy or unreachable my number..I have to enable flight mode,after that sim becomes active..As network bars in mobile show full, I cant know when my connection is gone, I recognise this problem accidentally if i am going to make call. My previous A71 also had same issue with jio sim, airtel or vi sims working fine...Jio store has no solution, dont know other non samsung android though.iphone has same issue with jio sim. Any one facing it or any solution??
I am using S21 FE with Airtel sim . S21 fe had so many network bands so It supports all international bands . Calls , 4g+ ,5G everything works flawless. I got a maximum of 60mpbs in my city
I'm using Jio Sim in my S21 FE and I haven't encountered any such problems in my device. My last device was also A71 which had no such problem. Try re inserting the SIM properly and make sure it is in 1st slot, that should do. If you found this helpful, please accept this as a solution by clicking on 3 dots of the comment.
