Tata docomo is the worst mobile operator compny in india. very poor internet connection. everytime it just shows H not H+ ad H+ is needed for proper operation of internet connectivity.
it just shows the cheaper internet plans/packs but when you use it you will realize the fact.just opens the same website from tata docomo and same website from some other operator like airtel, idea, vodafone you will see the data reduction is 40-50% more than as compared to other operators
covrage:- network covrage is very poor in the top cities than you can imagine the coverage in villages.
