4G network issue

[itsadiaditya]

My airtel 4G internet gets disconnected automatically. When I switch ON airplane mode and then OFF it, internet starts working but after 3-4 minutes of usage, its again disconnected. This problems continues whenever I use Airtel 4G internet. I also checked my SIM in other device but this problem occurs only in my device. What should I do ?

Please solve this issue in your new software update as soon as possible.

Device- Galaxy M31 

Model - SM-M315F/DS

May be Airtel 4G networking strength not very good in your area.

I've also checked my airtel SIM in other device, its working fine, network strength also good. Later on when I insert it back in my device, its starts disconnecting after every 3-4 minutes.
