Tata docomo is almost new mobile network operator in GSM networks. Its networks quality is good in city areas but not as much good in rural village areas. I am specially using tata docomo for internet for awesome and daily 100 messages offer. This is specially for lovers for chatting and messaging at low cost. but with the passage of time this service is not availble anymore and the coverage area is not covering every area of the country. I have faced no connection situations when I needed to make the call te most. I am porting mumy number to vodafone.
