Rumors of pager mode

There is a widely circulated view on the Internet:

Pager mode is also called "Do Not Disturb Mode". In this mode, the mobile phone will enter a "fake shutdown" state, LCD and other devices will be powered off, and all functions that need to use the operation interface, such as calling, texting, surfing the Internet and inquiring, will be banned, but all missed calls will be quietly recorded on the mobile phone.

When the owner returns to the normal standby state, he can check the record of missed calls and deal with it accordingly.

When the owner returns to the normal standby state, he can find the call records of his own calls, and he can also choose whether to reply.

What's even more amazing is that under the "fake shutdown" state, the mobile phone can still receive important information, automatically prompt and pop up new short messages, keep in touch with the outside world, and realize the function of all-weather pager. Under normal circumstances, mobile phones need to constantly search the network. During the call, mobile phones and LCD devices consume a lot of electricity, but in this paging mode, mobile phones save a lot of electricity. Especially when there is no electricity, this function is precious and considerate.

In fact, if the mobile phone doesn't contact the base station for a period of time, the base station will think that the mobile phone is out of power or service area, so the mobile phone can't receive the information from the base station. According to this statement, the pager mode will have the same function as the airplane mode.

This rumor has been circulated in various mobile phone forums and even encyclopedia websites, and the initiator is still unknown.
