AT&T has published tips on how their iPhone customers can minimize international data charges when traveling overseas:
Be sure to download and install the latest version of iPhone software from iTunes.
- Make sure Data Roaming is turned “OFF.” To check this, tap on Settings>General>Network>Data Roaming (Fig. 3).
- Utilize a Wi-Fi connection instead of 3G/GPRS/EDGE to browse the Web, download data, or check e-mail. Wi-Fi hotspots are available in many international airports, hotels and restaurants.
- 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” (Fig. 4). Consider Purchasing an International Data Package from AT&T. (Don’t cancel the plan immediately after returning from the trip. Wait 90 days so that all the international data charges have been reported to AT&T. Otherwise, you will be charged the more expensive data roaming charges.)
