I am using this network for more than 5 years and on that basis I want to share my experience on this network.
As the network is concerned its very poor, While travelling it gives trouble.Voice calls gets disturb many times.If we consider Internet provided by this network then 2G network is quite impressive than others.Internet speed in 2G is not that much bad.And customer service is also not that much good.Its ok. One of the best thing with this network is the recharge and offers are really affordable to everyone.
