About this episode

Have you ever wondered why this feature exists on our devices, and what purpose it serves beyond just flying on airplanes? The main function of Flight Mode is to disable your device's cellular radio. This includes the mobile network as well as 4G or 5G connections. That of course means you can’t receive voice calls or text messages. Why do we have to activate it when flying then ?
