I am using this airtel 4g from one years in pune.
Talking about the network, 4G is working very well in mostly all regions of pune.
And if one would ask me ask me that how many stars u would love to give to the airtel 4 g network I would tell that I give more than five stars if I get the privilege to rate in such manner. this is worth full in true sense.
I love airtel serviceability of such a superb speed only its lacks in TATKAL timings and may be its quite obvious becoz the are more than anything users using airtel network.its too good.
