Tata Docomo — Re-registration of sim

Address:East Singhbhum, Jharkhand

The function of my mobile no. [protected] has been suddenly stopped from 13.07.2015 without any intimation from the service provider, reason for which is unknown, although sufficient money is there.

It shows that the "sim registration failed".

Why it is failed & what i have to do for re-registration & why the service provider is not validating the same? Your immediate action for re-validation of this sim is highly appreciated.
