Providers have published tips on how their iPhone and iPad customers can minimize significant international data charges when traveling overseas. For the unknowing user, these charges can be incurred without their knowledge. Be certain that Data Roaming is turned "OFF." To verify this, tap on Settings>General>Network and turn Data Roaming "OFF." Utilize a Wi-Fi connection instead of 3G/GPRS/EDGE to browse the Web, download data, or check email. Wi-Fi hotspots are available in many international airports, hotels and restaurants. If you will be traveling for an extended period of time, consider checking with your provider for a short-term international data plan. iPhone users might consider downloading applications such as Line2 from Toktumi, Inc. This free application allows users to talk on their iPhone through Wi-Fi without incurring any charges.
