I have been using Tata docomo more than 3 years from now. For the past 6 month I am facing very hard time with the tata docomo service. They are totally zero in terms of customer support, network coverage, technology improvement and other stuffs. I’ll soon choose other service providers, since Tata docomo network coverage going worse day by day.
In my view, don’t go for Tata Docomo, rather than choosing tata docomo, go for Aircel, Idea.
