Network issues...

[Bishal17]

After updating my Galaxy F34 to the August security patch,it is facing serious network issues.The SIM1of my device,which is airtel,is being automatically turned off.So there is no network.I have restarted the device many times,the issue fixes.But after some time the issue again happens.What to do now?

The SIM 1 is not showing.Instead it's showing the useless SIM VI.And there is no option to turn the SIM 1[airtel] on,even though the SIM is inserted on the device.It is showing Emergency calls only!

Please help me to resolve this issue.

The last screenshot shows that the SIM is avaliable(after restarting my device).
