I am using Tata Docomo mobile network and I am not completely satisfied with the service of Tata Docomo. I know that the call rates, internet pack are cheap as compared to the other operators but what will I do without the network coverage as in maximum areas the coverage does not comes . It comes only in the main city areas . Docomo should improve their network and all otherwise we the customers will be very dissapointed and have to port our number to the other operator.
