Tata Docomo has failed to prove itself. While it started the business, the network quality and internet speed was aspected to be same as you could have find with Tata Tele services CDMA network. However it has disappointed completely. From day one, I have been facing the issue, especially with Internet speed,
Later on, after introducing 3G service, it has bocame the nightmare. Yiur data is drained like anything result is 0. Recently I recharged with 150 MB data pack during local broadband outage for a day. Surpiringly, that data pack got over with just one application update from playstore. I double checked tha app and it was merwly 19MB in total size.
Must say never ever use it again. Better you go with Vodafone or Airtel. They are also not the best but atleast you get what tou pay for.
This telecom company ruining the prastige of Tata.
