This time, i managed to get hold of a simple hack (Unfixed bug by Reliance) using which you can activate and use GPRS for FREE with 2 GB monthly data cap on your mobile phone. Moreover, it works for both postpaid (No Guarantees) as well as prepaid customers.
In order to access FREE GPRS, you need to dial *123*099# from your Reliance mobile phone. After following the on screen steps, you’ll then receive a confirmation sms regarding the activation of this service.
Note: This trick is working in Rajasthan, Kerela, Punjab, Maharashtra, Karnataka, Gujrat, Delhi and Mumbai (Some users may face problem). If you are not from one of these states then do mention you state/city in comment form along with your view point.
