We just returned from a fabulous trip, and I had intended to give my partially used Europa phone card to another traveler on our way out of the country, but forgot about it.
If you are interested, you can send me a private message. I think the card still has quite a few minutes remaining. It was originally 5 Euro card (which I think was 250 minutes). We used it a little, but I think there are at least 200 minutes left.
