We have Verizon and android phones. In 2013, we did a sailing trip in the british virgin islands and I opted for the international data plan for that month. In December, we went on a river cruise mostly in Germany and opted to get prepaid SIM cards in Germany at the start of our trip. (one data only, one data and voice just in case). And I've started reading this forum to figure out what my options might be when we do an Asia cruise next year. I'm ok with my options when I'm in one country, but multiple countries on the same trip adds complexity (for me, as tech isn't my forte ;-)
