I remember when I bought a tata docomo sim I was so exited to be a part of this network the service was so good and even the tariff plans plus the internet speed I remember even at 2G it was so fast to surf later as the technology developed the different network providers started giving better services even then I sticked to this network expecting a better service from them even today there is no 3G at my state from tata docomo side I am thinking to switching the network
