I am using tata docomo since one year and I have not faced any problem yet. Network coverage is very good.
There is no problem of Calls drop. The plans offered by docomo is very good and economic. I also use internet of this and all the packs either 2g or 3g gave me good speed.
Rate cutters packs cuts the bill very much and these are also cheap. Sometimes customer care executives calls and tell about the best plans. This network is better than other networks.
I am satisfied with this and recommend to others also
