Airtel was one of the best mobile operator companies but from the past 1-2 years the data plans, tarrif plan and the other recharge plans are not that much good as compared to other operators. If we look at its internet data plans they are more costly than data plans of other service provider, internet speed is also not that much good as compared to other operators like idea and tata docomo which I am using. Now if we look at its network and call quality these two are good that is every place we get a good network.
