I am using Airtel SIM from last 7 Years in Rajasthan, It provides me a good coverage in so little villages with good network and 3G access. I use other network But not get coverage like Airtel.
Its too good.
But one thing that can be beard by consumer that higher Rates and plan. Airtel not attract problem like call drops etc. providing good network consistently without any problem.I always suggest my friends to take at least one connection of Airtel for personal use.
