Alternatively referred to as flight mode, airplane mode is a mode available on electronic devices, such as cell phones and tablets, that disable all wireless communications without having to turn off the device. During a flight, airlines may request electronic devices be turned off or switched to airline mode to prevent any possible interference with the airplane's communication systems while in flight.
While in airplane mode, a cell phone will not be able to send or received texts, send or receive calls, or access the Internet. Tablets also will not be able to access the Internet while in airplane mode. Any other device placed in airplane mode will not be able to utilize any wireless communication signals.
Other actions, like playing a game or using an app that does not require access to the Internet, will still work while the device is in airplane mode.
