    • Turn data roaming “OFF”: Be sure to download and install the latest version of iPhone software from iTunes. To turn data roaming “ON/OFF” tap on Settings > General > Network > Data Roaming
    • Utilize Wi-Fi instead of 3G/GPRS/EDGE: Wi-Fi is available in many international airports, hotels, and restaurants to browse the web or check e-mail. You can also use VoIP services (e.g. Skype) to make calls.
    • Turn fetch new data “OFF”: Check e-mail and sync contacts and calendars manually instead of having the data pushed to your iPhone automatically. This way you can control the flow of data coming to your iPhone. To turn off the Auto-Check functionality tap on Settings > Fetch New Data, change Push to “OFF” and select to Fetch Manually.
    • Consider purchasing an international data package.
    • Reset the usage tracker to zero: When you arrive overseas, access the usage tracker in the general settings menu and select reset statistics. This will enable you to track your estimated data usage. To reset Usage Tracker to Zero, tap on Settings > General > Usage > Reset.
    • Do not download video on your iPhone or lap top while traveling. This will help you avoid some of the most expensive data charges. If you want to stream a movie, music video, or TV show on your phone, go to a Wi-Fi hotspot and download movies over that network.
