Does Apple send and receive WeChat after the phone is in flight mode?

Unable to send and receive. The function of flight mode is to turn off the signal transceiver of SIM card, so the mobile phone will not send any signal in flight mode. If you receive a WeChat message during this period, you will close the flight mode and receive data signals.

Mobile phone flight mode 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. Some mobile phones have this function, which can turn off the signal transmission and reception of SIM card.

The flight mode function in some mobile phones can be realized by some software, such as the aviation mode in the system tools in S60 software. This mode can turn off the function of the SIM card, so that the mobile phone is in a state of not sending and receiving signals, and does not affect the operation of other functions of the mobile phone (generally, the mobile phone cannot operate without the SIM card).

On September 29th, 20 14, european aviation safety agency (EASA) said: China plans to allow mobile phones to use airplane flight mode in 20 16.

When the GSM/GPRS module of the mobile phone is turned off in flight mode, 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 make international calls of 1 12, and may not support1/20, etc.

Because the paging signal of 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 mobile phone signal are turned off, and the mobile phone can continue to use other functions, such as looking up the phone book, enjoying articles, watching movies, playing games, etc., so it is called flight mode. Most of the power of the mobile phone is consumed by the signal. Turning off the signal in flight mode is very energy-saving.

Automatic flight

Principle: Turn off the wireless signal of the mobile phone, and the system judges that the mobile phone is out of power or turned off. Later, some software authors realized super flying and continuous super flying according to this function.

Tip: If someone calls you, they will remind you to turn off your phone.

How to achieve it: Generally, SP phones can achieve it by themselves, while others need the help of third-party software.

Super flight

Principle: weaken the cell phone signal, so that the cell phone and the base station can't contact normally, and the system will misjudge that you have reached a place with bad signal.

Tip: when someone calls you, the system will prompt "unable to connect" or "out of service"

How to realize it: SP system can't realize it by itself, and it needs third-party software, such as QPTools.

non-stop flight

Principle: If the mobile phone can't contact the base station for a long time, the system will judge that you have turned it off. This time interval is usually 1 hour, so a simple super flight can only last for about an hour, and then the system will automatically judge that you have turned off your phone. In order to continue the flight, it is necessary to contact the base station once within the time specified by the system to reactivate the super flight.

Tip: same as "super flight"

How to achieve it: SP system cannot achieve it by itself. If you want to use third-party software, such as QPTools, you can contact the base station every 30 minutes or 1 hour.
