Where do I live, docomo service is best, and sometime I get 3g internet service on 2g internet pack(i like that most)and also the thing I dislike is still there is no 4g service for tata docomo, and also it cost less than any other mobile operator.
But anyways I like it more than any other mobile operator, i dont know any other mobile operator service in other cities, how they work in other cities, according to me where I live most of the people uses docomo mobile operator for their daily purpose in their life
