Hi,
I am using Fastrack Supreme 20 Plug& Play type, i would like to enable GPRS how it is possible. Please give me the solution.
Arise.
How do you mean, “enable GPRS”? 
AFAIK, there’s nothing to specifically “enable” GPRS - it is a GPRS-capable modem!
You will, of course, require a suitable SIM and suitable network subscription - but that’s nothing to do with the device.
