Using a Cingular MPx220i with AT&T?

[Rick Stenson]

I have a SMT 5600 that I purchased with AT&T. I was just given a Brand New unlocked MPx220i that is configured for use with Cingular. I have put the SIM from the 5600 into the 220 and am able to make and receive Phone calls perfecetly. However the Data Connection does not work. (Internet, Email, etc.). Does anyone know if it is possible for me to get the 220 to work for data through the AT&T network, and if so can you tell me how to configure it?

Please no flames about why would I want to switch. I just need to have both available.

Thanks.

The settings from your MPx220 should be the exact same as the ones you are using in the SMT5600. If the MPx220 is configured for Cingular, then you will need to change these to match your SMT5600.
