Turning Airplane mode on or off
In many countries, you are required by law to turn off the phone while
on board an aircraft. A way to turn off the phone function is to switch
your phone to Airplane mode. When you enable Airplane mode,
all wireless radios on your phone are turned off, including the call
function, data services, Bluetooth, and Wi-Fi.
To turn Airplane mode on or off, you can:
Press and hold POWER, and then tap Airplane mode.
From the Home screen, press MENU. Tap Settings > Wireless &
networks, and then select or clear the Airplane mode check box.
When enabled, the Airplane mode icon ( ) is displayed in the status
bar.
When you disable Airplane mode, the call function is turned back on and
the previous state of Bluetooth and Wi-Fi is restored.
