AT&T has sent email messages to iPhone customers to remind users that international data usage is not covered under your existing U.S. data plan.
Your iPhone provides access to email, Visual Voicemail, Web browsing and other applications that can use a significant amount of data. It’s no surprise that you might find yourself using more data than you thought. AT&T wants to let you know of some easy ways to help minimize data usage charges when traveling overseas.
• Turn Data Roaming “OFF”: Be sure to download and install the latest version of iPhone software from iTunes. These software updates will enable the ability to turn on/off data roaming when traveling outside the U.S. By default, this setting will be in the “OFF” position. turn data roaming “ON/OFF” tap on: Settings>General>Network>Data Roaming
• Utilize WiFi instead of GPRS/EDGE: WiFi is available in many international airports, hotels and restaurants to browse the Web or check email.
• Turn off your iPhone’s “Auto-Check” Function for Email: Data usage from email can accrue quickly. Check email manually using WiFi instead of having emails downloaded 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>Mail>Auto-Check and select Manual
