yes.

flight mode means that you must turn off the mobile phone or turn on the flight mode that comes with the mobile phone to cut off all communication signals, so as to prevent the transmission and reception of mobile phone signals from affecting the flight of the plane. Some mobile phones have this function, which can turn off the signal transceiver of the SIM card.

this mode can turn off the function of the SIM card, so that the mobile phone is in a state of not transmitting and receiving signals, without affecting other functions and operations of the mobile phone (generally, the mobile phone cannot operate without the SIM card).

Purpose

When the GSM/GPRS module of the mobile phone is turned off, the mobile phone will not actively send paging signals to the base station, that is, it will not try to contact the base station, but it can generally make emergency calls (similar to the principle of no sim card, in this mode, the mobile phone can generally dial 11, 12, 112, etc.).

Because the paging signal of the mobile phone will interfere with the electronic equipment on the plane, it is not allowed to turn on the mobile phone on the plane. In this mode, the related functions of the mobile phone signal are turned off, and the mobile phone can continue to use other functions while being turned on.

If you check the phone book, enjoy articles, movies and play games on your mobile phone, it is called flight mode. Most of the power of the mobile phone is consumed by the signal, and the signal is turned off in flight mode, which saves electricity very much.
