Function and use of mobile phone flight mode

The flight mode of mobile phone is also called aviation mode, which means that the mobile phone must be turned off during flight to avoid the influence of the transmission and reception of mobile phone signals on aircraft flight. This article will introduce the function and usage of mobile phone flight mode.

Turn off the telephone communication function

Flight mode is to turn off the telephone communication function, that is, you can't answer the phone and send short messages, have no signal contact with the base station, and don't try to contact the base station.

Turn off the cell phone signal

Because the cell phone signal will interfere with the electronic equipment on the plane, it is not allowed to turn on the cell phone on the plane. In this mode, the related functions of mobile phone signal are turned off, and the mobile phone can continue to use other functions, such as checking the phone book and enjoying articles and movies on the mobile phone.

Turn off the SIM card function

Some mobile phones have this function, which can turn off the signal transceiver of SIM card. And it is realized by some software. For example, the system tool of S60 software has aviation mode, which can turn off the function of SIM card, so that the mobile phone is in a state of not transmitting and receiving signals, without affecting other functions of the mobile phone (generally, the mobile phone cannot operate without SIM card).

Power saving

Most of the power of the mobile phone is consumed by the signal, so turning off the signal in flight mode is very energy-saving.
