@Sapney and @chetangor7, Thanks for your info. I had really bad experience with airtel till I contacted the Nodal OfficerI did sms "INTERNET" to 121, and got a service request number yesterday, but till 11 AM today it was not activated. Calling 121 (which is now charged at 0.50 per 3 mins) turned out to be a joke, as they didn't know that this Rs. 98 pack was there for postpaid. So I directly called the nodal officer @9987234865. The guy was helpful. He had initially told me to wait for 24 hours as my request was already in their system, but then he called me again in 2 mins and activated GPRS Rs. 98 pack within a minute. I also confirmed from him that the pack has 2GB data free for 1 month with 50kb pulse.
