I used my first smartphone which I used the airtel sim number in 2009
IN Past day the airtel provide the best 2g speed and high data in low price but in nowdays the data charge is very high and the speed is not good it gives only 5 to 6 kbps which is not good to use in smartphone
And the second thing that the call rate of the operater is so high
The network is not good in the UP east I belong from UP east
I started hating this operator when I lost my sim card and required a new sim card with my old number he said the number is not available because number was vip so he sell my number to another user
So guy I would never recommend the airtel to use
