I just checked with Verizon. They have three different international plans. 1) $100/month (screw that!) 2) $10/line per day used (better!) 3) Pay as you go. $1.79/min for calls. 50¢ sent SMS/50¢ MMS and 5¢ received SMS/25¢ MMS (I think we have a winner!)

Thanks for the replies. The pay as you go seems the best option for me since I wouldn't use the phone more than a half dozen times.
