Turn Airplane Mode On or Off auf Android
Airplane mode is a single system switch that disables every radio on your phone at once: mobile network, Wi-Fi and Bluetooth. It exists mainly for flights, where active radios can interfere with aircraft communication, but it is also useful whenever you want to stop all connectivity quickly, for example to save battery or avoid interruptions.
On Android, the setting sits in the network section of the system settings. Follow this path: Tap on Settings ➔ Tap on Network & internet ➔ Enable or disable Airplane mode. The same toggle is usually available from the quick settings panel you open by swiping down from the top of the screen, which is faster once you know where it is.
Turning Airplane mode on cuts mobile signal, Wi-Fi and Bluetooth immediately. Some phones let you re-enable Wi-Fi or Bluetooth manually while Airplane mode stays active, which is handy on a flight with onboard Wi-Fi. Turning it off restores your previous connection settings, but the phone still needs a few seconds to reconnect to the mobile network.
If only your mobile data stops working while Wi-Fi still connects fine, the issue is likely a separate data toggle or a carrier setting, not Airplane mode. In that case, check the mobile data switch directly instead of toggling Airplane mode on and off.
