Internet Access on an Airplane

Airplane mode turns off the iPhone cellular, Wi-Fi, Bluetooth, and GPS transmitters and receivers to avoid interfering with aircraft operation. Airplane mode disables many of the iPhone features. In some countries or regions, where allowed by the aircraft operator and applicable laws and regulations, you can turn on Wi-Fi while airplane mode is on, to:

ÂÂ Send and receive email ÂÂ Browse the Internet

ÂÂ Sync your contacts, calendars, browser bookmarks, and notes over the air ÂÂ Stream YouTube videos

ÂÂ Get stock quotes ÂÂ Get map locations

ÂÂ Get weather reports

ÂÂ Purchase music and apps

You may also be allowed to turn on Bluetooth to use Bluetooth devices with iPhone.

For more information, see “Airplane Mode” on page 187.

VPN Access

VPN (virtual private network) provides secure access over the Internet to private networks, such as the network at your company or school. Use Network settings to configure and turn on VPN. See “Network” on page 193.

Personal Hotspot

You can use Personal Hotspot (iPhone 4) to share an Internet connection with a computer or another Wi-Fi device—such as an iPod, iPad, or other iPhone—connected to your iPhone via Wi-Fi. You can also use Personal Hotspot to share an Internet connection with a computer that’s connected to your iPhone via Bluetooth or USB.

Note: This feature may not be available in all countries or regions. Additional fees may apply. Contact your carrier for more information, including the number of devices that can share an Internet connection at the same time.

If the Set Up Personal Hotspot button appears in your General > Network settings, you first need to set up the service with your carrier. You can contact your carrier by tapping that button.

Personal Hotspot works only if iPhone is connected to the Internet over the cellular data network.
