The AT&T Global Wi-Fi app is required to use the international Wi-Fi service included in your qualifying package.
Download the app before you travel, if possible, by clicking the link in the AT&T welcome message from your smartphone or tablet, or from the Google Play Store. Cellular data charges may apply for download and usage.
Once you have downloaded it, open the app to register. Setup is quick. Simply follow the directions on your device.
If you purchase your package with a future effective date and download the app in advance, you can complete setup of the app as soon as your package is effective.
