Turning airplane mode on or off
In many countries, you are required by law to turn off wireless devices while on board
an aircraft. A quick way to turn off wireless functions is to switch your phone to
airplane mode.
When you enable airplane mode, all wireless radios are turned off, including the call
function, data services, Bluetooth, and Wi-Fi
® . When you disable airplane mode, the
call function is turned back on and the previous states of Bluetooth and Wi-Fi are
restored.
1. On the Start screen, slide to the left.
2. Tap Settings > airplane mode.
3. Tap the Status switch to turn it on or off.
When airplane mode is on, you'll see the icon in the status bar.
