Turning flight mode on my device on or off
You can turn off all network connections on your device so it can’t cause any interference with sensitive equipment in a plane or a hospital. It's called flight mode. You can still use your device when flight mode is turned on, but you can't send messages, make calls or use the internet.
1. Find "Settings"
2. Turn flight mode on or off
Depending on the current setting, the function is turned on or off.
