In the past 8 months I have used my Razr in London/Paris/Munich with zero problems.
My carrier is Cingular.
You just need a quad-band GSM phone.
BTW, text messaging and photos work abroad just like you were at home.
I suggest that you consider an UNLOCKED quad-band GSM phone, or have the phone unlocked after purchase. (Phones are generally sold locked so that the owner can't switch services by simply swapping sim cards, without buying a new phone.)
I currently have an unlocked Cingular Treo 600 soon to be replaced by a 650 or 700p so that I have Bluetooth before my 650 (the car!) arrives. I've used the 600 throughout SE Asia, Europe, and Latin America by popping in a local sim card as soon as I land in a new country. Advantage is that calls, both local and back to the US, are far less expensive than using the Cing card, and that all my Palm PDA functions are preserved.
Further, outside the US, incoming calls on a local sim card are generally not charged against your remaining minutes. Disadvantage is that the new sim card comes with a new cell number so that you have to inform folks back in the states (I use email) of your new number.
Hope that helps...
