Hello Friends, I am going to share my experience with you today. I have a 3g sim of tata docomo. And I live in Chandigarh. Here its network is very good. And the Internet also runs very well. But sometimes when I go to the basement Or if I am driving, then my call does not seem to be. Other people make calls, they say that your call does not seem to be quite often. And once I went to village, then there was no network of its own. I had to face a lot of problems. But its prepaid plane is very economical with all other companies. Just come to its tata docomo 4g service And the network becomes stronger.
