Very good network.I am using Tata Docomo for 1 years .It offers best service in pune.It’s 2G and 3G coverage is good but sometimes 3G network is not proper .The best part of Tata Docomo is its plan’s it offers both data and talktime at good price.
When I had some issue the customer care response was good at preety time. Till now I have not faced in problem with Tata Docomo. I would recommend people to use Tata Docomo who use heavy amount of data.
