My name is yneeraj I am sharing my personal experience with you that about tata docomo servers this network is like with out signal at our locality and if there is a signal when we on the packed data connection it will come and after 2 minutes it will goes into the E type signal and some times it will not comes the E network also and some times emergency time when we call some one the calls also got jumped to someone's number and all of these issues I have sorted my another sim to idea and also there is another thing about this network means the no sending of messages to another these takes late to receive or send any messages.so I tell to this network that give more attractive offers and good services and best signal if you give all this to all you will be number 1 when compared to all
