Airtel 5G/4G causing unstable gameplay during flight/atc controlling

Device One Plus Nord AC2001
Operating system Android 12 , 26.3.1

I am using the Airtel 5G network, and I am still not receiving any response from the controller during my flight, and vice versa the same applies when controlling on Expert server, I am unable to hear any response from the pilots. My network is running with good speed on other apps. Restarting also is not making much help the issue persists. I tried to use 4G network of the same Airtel, but the same issue is occurring on the device. I know this issue has been reported by many Jio users, but in Airtel also, the same is causing the problem till this version

See below from a few hours ago:

That topic is related to something else.

But Airtel and JIO are basically suffering from the same issue.
And generally;

Multiplayer games like Infinite Flight and others, with a high package rate - generally runs poorly on cellular. Especially cellular networks that prioritizes costs and speed, which checks out for both JIO and Airtel.
