I had been using tata docomo operator from 2012 which is of prepaid. The connection was very poor. They are just fooling the customers. We don’t even get a 3G at metropolitan cities like bangalore. Very very weak network connection. When we call customer care, they just fool us by pretending like they have the best network in the world. We are not fools to accept it. I only get 2G network wherever I go. Sometimes, NO SERVICE. I need to switch off and on my phone for so many times to get the network. I just ported my network. So guys, don’t ever buy a Tata docomo sim in your life.
