How can I reduce my AT&T iPhone bill when traveling internationally?
If you're taking your iPhone overseas you may have read horror stories of people returning home to thousands of dollars in wireless bills. There are several ways to reduce your charges when traveling abroad if you absolutely must have your iPhone.
First and foremost, be sure not to run up hidden data charges when traveling abroad. Select Settings -> General -> Network -> Data Roaming -> OFF. This will make sure that bandwidth is not being used by your iPhone without your permission.
