Hello! friends I am using airtel sim from last two years. Airtel is very good for network. You get mobile signels mostly every place. But net plans Are very costly. Before Some time airtel not connect with reliance jio network. But now its easly connect with reliance jio network. Airtel provide good net speed and good voice quality. Airtel to airtel plans also costly. Call drop complaint in this network is very less in comparision to other networks. In my view airtel provide best network and signal every place.
