In these years I have never seen network problem. the network very strong then other operator. in our village area in Gujarat there are several operator available like
Docomo, Vodafone, Uninor, TATA, BSNL but in all these Idea is the best network provider. The strength of ida network is very strong then other. Also idea provide 3g data plane in every where the net-surfing speed of idea is batter then other operator.
