Tata Teleservices (Tata Docomo) the Telecom unit is going to shut down as per sources, the officials are discussing ways to sell / surrender their spectrum holdings. In case you are using Tata Docomo services better port your number to other services.
The company was not doing well, for many years and now they want to close down and write off their losses. Most likely they will start the shutdown process soon probably in a month or two. Tata Teleservices has operation in 19 circles.
Tata Teleservices began its operations in 1996 (landline), in 2002 they launched CDMA, then in 2008 went with GSM (NTT Docomo joint venture). The NTT Docomo venture ended 3 years ago. The company is yet to officially announce the decision to shut down, once they do that the Tata Docomo customers will need to port their excising Tata Docomo number to other service provider.
Don’t think there are many Docomo users in India, but if you are using their services then better move out.
