I am Siva Rama Krishna, I am using Tata Docomo from 3 years.
It is best when compared to other operators in some of the points like talktime offers, local & STD call rates and web data offers.
It is week in signaling in most of the villages including my village far to Guntur.
When I came to my home my all friends who are mostly contact with me trough the network are disconnected.
So it is the only best suitable for cities and the villages those are having network towers.
Thank You.
