Hello International Businessmen who have very important international meetings to go to... (that was a HIMYM reference for an FYI)

I'm going to Europe this summer for about two weeks and was wondering if anyone had experiences with temporary international phones. Unfortunately I have Verizon, so I can't swap out a sim card. I think I've heard of prepaying for the minutes, and having it work in the country you're in?

Thanks a lot!
