I will be in Germany, Austria, Switzerland in early May. My cell phone won't work there. What is the best/cheapest way to call back to USA while traveling without use of cell phone? Last year we purchased a prepaid phone card, but couldn't get it to work with pay phones. Tried to use it from a hotel room and ran up a $50 bill in a few minutes. Finally found a western union store that had phone booths and allowed calls at very cheap rates (like $0.05 per minute.
Any better ideas?
