International roaming charges are so absurdly high that they force me to have different sim cards and an unlocked phone (extremely inconvenient). - A nonstop flight from Buenos Aires, Argentina (EZE) to a major city in California (SFO, LAX, SAN). I do this several times a year and the layover/recheck luggage after customs is a killer.
