[Resolved]  Tata DoCoMo Prepaid Card — Registration failed

Hi, I have bought my Tata Docomo number before 1 year ago and I had use it for 1 year but as per my business trip have to go out of state for 2 months and during that months I rarely do transaction and mine Docomo number is activate but its SIM card is not working so I have contact company center for the same and they told me to buy new SIM for the same number and which I did. But as per they said my new card is activate within one day but after one day time I try to on my mobile at that time it show this error message that SIM card registration is failed.

So, please let me know what that message want to say for my SIM.
And my number having enough fund in balance that thing also said by you company representative.
