If you followed my posts from end of December until early January, you probably know that I spent a significant amount of time talking to AT&T and Apple technical support reps, trying to get informed about how I can be using the Apple iPhone internationally without costing me thousands of dollars in voice and data charges. Well that process of getting informed, in and by itself, was quite a challenge, and finally I believe that I got the right information, and ended up signing up for one of international data provisioning plans which costed $59/month for 50MB of data.
Now that I am back to the U.S. it is time to pay the bill. So here is the result of my effort: I got charged for the international provisioning (the $59/month) and in addition, I got charged about $225 for international voice and data usage. It didn't take too long to get this corrected, and the $225 charges taken out of my bill, but it is ironic, and it is Murphy's law at its best.
So the moral of the story of my research about using the iPhone internationally, which started in early December and ended in late January, is that you really need an international provisioning plan, you need to be careful with the usage knowing that 50MB can go by pretty quickly, and finally you need to be on top of things in terms of checking and making sure you're getting what you thought you would.
