The cell phone companies are constantly tweaking their data, text and phone plans which can help you save when traveling.  Contact your cell phone company to see if your phone will work abroad (or if they will send you one that will) and before each trip check the cost of the various plans depending on your needs.  Cell phone rentals with either prepaid plans or pay-as-you-go plans are worth comparing too and we are happy to arrange them for you.  Also check out new apps that are available to help you compress the amount of data you download to help you save even more.
