I used to many mobile operators but I couldn't satisfied with all these .so I am looking for a new mobile operator so I am asking for my friends to advised me a better mobile operator than one of my friend advised me to buy tata docomo mobile operator .
I bought this mobile operator after using this I found that this is not an effective mobile operator . the network service of this mobile network is poor . it gave poor service in villages . it didn't work on hill stations . it is more expensive than others
