I am using airtel since my first phone. Airtel used to give 5 rs nop plan i. e whole day Internet free on mobile.then they introduced new gprs 15rs gprs plan on mobile as well as on pc. Means those days airtel was rocking for providing economic Internet plans. But these days you can observe airtel has highest Internet rates. I agree that they are providing high speed as compared to others but we indians want economic plan rather than high speed
