I used xcom global last spring in Rome and Athens. It worked good in major cities. One day I had a problem. I emailed them and they reset the system and worked fine for the rest of the trip. I got an extra battery so I could trade them out during the day. It was a great way to communicate back home without having to buy minutes or a international phone. I am considering using them again this summer.
