Hii guys I am subhojit and I will share my personal experience with you .
Now before I proceed let me tell you that I have used Tata Docomo for 1 year and it was the worst experience ever .
Their technology is not updated atall .
The net connection is very very slow and they dont even have 4g .
4g which is a very important factor now a days and they are not updated with it .
Which means they are not adapting to changes .
I want to say that it is a very bad connection and sometimes getting signal is a major problem .
In remote places we will not get any signal .
I went to my friends place in ghotorpukur and there was completely no network at all .
Infact I had use my friends mobile to make a call .
The connection is so bad that it becomes impossible to get connected from remote areas .
I would never suggest anyone to choose Tata Docomo .
Worst experience ever
