Does it cost money for Apple phones to send text messages to each other?

Apple phones don't need money to send messages to each other, because the system uses "imessage" to require traffic above iOS5.

Apple's mobile phone has several hidden tricks:

convert

In the drop-down menu or the menu on the left, search the interface, and enter the corresponding currency, kilometer, weight, size and other codes to get the corresponding values.

App Store problem recovery

When we use the App Store, we may encounter the situation that the app cannot be downloaded or the store page cannot be refreshed. We only need to click any option at the bottom of the App Store for ten consecutive times to force a refresh, and all kinds of strange problems will be solved.

Compared with the night mode, the white point value can be reduced.

Turning on the display adjustment interface to reduce the white point value will make the mobile phone dim at night and reduce the damage of the screen to the eyes.
