Airtel works on NSA, So If you are connected to 4G, It shows 5G sometimes (But works on 4G spectrum), And 4G is not unlimited, that’s why it is consuming data from 4G data pack…
Try to navigate to different location and check if network Moster app says NSA 3500
If it shows that, that means you are connected to 5g
If not then you are disconnected from 5G and 4G data being used
