Tata Docomo Mobile Operator. This is one of well known company in telecommunication.there is no good experience with it.no good network coverage no good connectivity no good plans bad customer support, there is bad quality voice calling you cant heir from other side. Tata Docomo is not good as they provide only good local network but it’s services is not good in roaming or other cities. It’s not working in most cities. They need to provide free internet in roaming. and cost is moderate and metro area is not responding and Switch off the phone tells him that.
