This is because the 3g data modem which you have is locked by BSNL...
But BSNL will not provide the lock code to you as you have bought this from BSNL...
If you know any technician from BSNL, they may know the lock code....

Dear Anand
Welcome to Fixya Support.
Generally Micromax mmx 310g USB modem is mainly designed for BSNL sim and it has inbuilt Network Code Key(NCK) of BSNL. So for installation of any other Network Code key you have to contact network operators(Vodafone,Airtel,Aircel )and they will generate Network Code key for your device.
I think it helps. Let me know
Ask your micromax dealer. Maine jab 310g bsnl modem khareedi thi to dukandar ne unlock kar ke di thi. Ek bar dukan par tatadocomo se chala kar bhi dikhai thi.
