I have a 2 years old Samsung X100 phone, having an Airtel Prepaid Connection. Recently, I called the customer care for activating my GPRS. I recieved settings within some days and the older settings were overwritten. But whenever I try to send any MMS it says "Network Rejected". Also, the Customer Care only says that "our GPRS is activated". Also, how do I go about activating my WAP.
