Avoid roaming charges. If you travel abroad, there will be corresponding roaming charges if you open data traffic. If you don't buy a local mobile phone card or forget to apply for roaming package, you can switch your mobile phone to flight mode to avoid roaming charges, and then turn off flight mode when the hotel is connected to the wireless network.
Network reset. When we pass a place where there is no signal, the mobile phone will encounter network failure or disconnection, which will not be restored for a long time. It's no use worrying at this time. You might as well turn on the flight mode and turn it off later. Through such a network reset, you will find that the cell phone signal is back.
Prevent children from playing with mobile phones. If the child wants to play with your mobile phone and you can't refuse. It is recommended to turn on your flight mode before giving your mobile phone, so that there is no signal and no network. No matter how the child presses or clicks your mobile phone, there will be no mistakes.
Reduce radiation. If you put your mobile phone on the pillow at night, it will produce great radiation to your body. If you don't want to turn off your phone, turn on the flight mode of your phone, which can not only greatly reduce the radiation of your phone, but also help you sleep peacefully without worrying about the alarm clock not ringing. Of course, if you want to be alone without being disturbed, you can also turn on the flight mode. When the airplane mode is turned on, there is no mobile network, but you can still connect to the wireless wifi network, which is not interfered by the mobile phone and does not affect surfing the Internet and playing games.
