I use the airtel service till 3 years .At the middle I also started to use other network service because I thought that may be the other network is more better than the airtel network.But after few month I really understood that over all my airtel network service is better for me.
Now about its speed, I can say that the speed of airtel is also super in quality . Because as I use other’s network service only airtel which was not disconnected for time .But other services are so many time ( at the village, in the room etc.) disconnected & I feel boring. So want to say that you can use this airtel network service .
