I have tata docomo connection from last 3 years. It provides very good plans of internet and calls as compared to others. Also when in cities it provides very fast speed of internet.
But at many places it has no network. Problem occur when I travel to a new place it shows no service which causes a lot of problems. Also in hilly areas, no service of tata docomo.
It is best for the people who don’t travel & live in cities. Otherwise very poor.
