You're addicted to your iPhone - you have to check the e-mail, see how your stocks are doing, find out if it's raining back home, and of course, read the hometown paper on the web. Naturally, it's going with you on your overseas vacation. But using your iPhone outside can be expensive; there are stories floating around about four figure bills.
AT&T offers domestic phone plans that include both voice and data services. Your plan probably gives you four hundred or more minutes talk time and unlimited data usage, and on the weekends and evenings, calls are virtually free.
But outside the U.S., voice and data are billed separately and charged by the minute or kilobyte. Keeping your phone bill under control involves understanding how the billing works and how to manage your phone's use of data and voice services.
