Thanks, I am trying to achieve the same thing as noted by you. I am trying to get free minutes using my data. In the call back list I am unable to enter any numbers, it gives me only 3 options. 1. Not set 2. 200-4-Google Talk 3. my mobile number There is no option for me enter any other number as call back number on DC. could you please explain the steps if you don't mind please?
