I was using Tata Docomo connection for 1 year. Firstly the installment charges are too much. Then they have offered me a 3 MB/s speed( I was paying for 3MB/s). Then after installation what speed I got is roughly 100 KB/s. Then I went to my nearest tata docomo shop and complained about speed they replied cassually that we will fix the problem but problem weren’t fixed and I switched my connection. So if you are going to take tata docomo connection I wont recommend it.
