I am using Tata Docomo for many year since 2years but till now my experience with tata docomo is not good because there recharge pack is too costly sometime there network is very slow in internet it work too slow.Many time my talktime money is deducted but when I complain them they say that you have activated some activities like caller tune etc.but I have not activated it in this way I lose my money.I am not happy with there service.
