I am using idea mobile operator from last three months and I am not going to recommend anyone to use idea mobile operator because of its pathetic services. The only good thing about idea mobile operator is its network range, you will get the network of idea almost all the places but when it comes to customer service and internet so idea mobile network is really bad, you will get downloading speed of 30 - 40 kbps in 3G network, now you can imagine how worse the internet of India Mobile network operator . I suggest that there are so many good option available in mobile operators like airtel, bsnl so go for them.
