I used this network few months back.
One of my friend suggest me this network because he said the call rates and internet pack are very cheap with tata docomo.
So I port my number into tata docomo.
The very first problem
I faced with this provider is that when I activate 3g internet but the speed of 3g is even worst than 2g and when I called customer service to file a complaint about this , then they told me that my pack is expired and that was the biggest lie I have ever heard in my life till today , because the pack activated on my phone just 2 hours back. I ignored it but when I got my first bill I was about to get a heart attack , they send me the bill of 5613 inr.
I paid this bill in installments .
So I suggest you guys please never ever choose this network.
Thanks.
