I am using tata docomo for about 2years but I had now realized that I had done abig mistake. It has a very bad network connection and services.
The only thing good about tata docomo is its cheap rates and plans as compared to other network operators like idea, airtel etc. but these too seems to be not much effective due to the bad network.
It has some other problems also like if I go in my room then in lost the connection and then I am not able to make a call or do something which creates a big problem and then I have to come outside to do that.
