Yes, it's a quad-band "world" phone. If there is GSM in the country it will work. But for now you'll be roaming internationally which cost boo-koo bucks. Check ATT's site for what each country costs per minute. Hopefully after the 30-day "free" cancellation period ends you'll be able to call ATT up and get them to unlock your phone. Then you can buy a SIM card in the country you are visiting and use your phone for cheap. Or you can get an "international SIM," like these <http://www.prepaidgsm.net/en/international.html> which cost a bit more, but are more convenient (and still cheaper than ATT roaming rates).
