Q. Can I use my nook while traveling abroad?
A. Yes, when you travel abroad, you can read any files that are already on your nook. You can connect to Wi-Fi hotspots that do not use proxy security settings, such those commonly used in hotels, and download eBooks and subscriptions already in your online digital library. You cannot, however, purchase additional eBooks and subscriptions.
Q. Will new issues of eNewspapers and eMagazines be downloaded to my nook while I'm traveling?
A. Yes, if you are traveling in the United States, or if you are abroad but connected to a supported Wi-Fi hotspot, new issues are delivered to your online digital library in both cases. When travelling abroad without Wi-Fi access, new issues are not downloaded to your nook (automatically or manually).
So no, it isn't international.
