How to use BSNL GPRS on Post Paid plan 325?

Dear People,

I am Using BSNL Post paid connection with Plan 325 In Maharastra Circle.

The plan Mentions that they've provided 5MB Of Free GPRS in this 325 Plan.

Please let me know how to activate/use the GPRS.

I've entered the settings (APN- gprswest.cellone.in) but it does not connect.. Does it need some activation?

Any one?

Send SMS :
GPRS to 53733

I contacted the bSNL exchange and they activated it.
Thanks.
