If the cell doesn't go over, get a phone card in the states!
They will work over there, but they will act as fewer minutes than the card claims, it will, however, still be cheaper than making international calls!

Also, don't know if you wear much Khaki, but oddly enough, they don't seem to wear it at all in Europe... Khaki seems the be one of the most obvious signs of an American tourist...

at any rate, have fun!
