Desire, World Phone capabilities


If traveling outside US, what if any are the options w/US Cell HTC Desire? Probably India, New Delhi area. Is there calling/data cards?
US Cellular does not have support over seas, from what I know. It would be best to contact customer service by dialing "611" from your US Cellular Phone. As far as I know, you would need to by a GSM phone (sim card) to work over seas.
