What is Airplane Mode? Airplane Mode is a mobile setting that switches off your phone or tabletâs connection to cellular and Wi-Fi networks, as well as Bluetooth. Itâs so-called because those radios may emit electromagnetic interference that can affect the operation of sensitive airplane instruments, or, according to the FAA, disrupt service in terrestrial cell towers, clogging networks with signals from the air.
