I am using airtel 4g from last 2 years.
The internet speed is very poor as it gives maximum 4 mbps downloading speed which is very poor as compared to other internet providers.
The connection is not reliable at all because of poor internet speed and service they provide.
The costomer service and support system is also very poor, I had complained several tines for the poor internet speed but tgey dont do anything and they are not sending any engineer for the solution.
Over all it is very poor internet provider.
