Airplane mode

When activated, this mode suspends the device's radio-frequency (RF) signal transmission technologies (i.e., Bluetooth, telephony and Wi-Fi), effectively disabling all analog voice, and digital data services, when implemented correctly by the electronic device software author.

The mode is so named because most airlines prohibit the use of equipment that transmit RF signals while in flight.

The Federal Communications Commission banned using most cell phones and wireless devices in 1991 because of interference concerns,[clarification needed] although there is no scientific evidence of such.

Messages are stored in memory to transmit later, once airplane mode is disabled.

Wi-Fi and Bluetooth may be enabled separately while the device is in airplane mode, as allowed by the operator of the aircraft.
