What does imessage mean for iphone?

Simply put, if the other party uses an Apple phone and you also use an Apple phone, you can turn on the iMessage function. As long as there is a network, you can use this function to chat for free, and it will also display the read and unread situations. The dialog box is blue.

This is an encyclopedia explanation: iMessage is an instant messaging software launched by Apple, which can send short messages, videos and so on. And the security is very high. IMessage is different from SMS/MMS service of operators. Users only need the data support of WiFi or 3G network to complete communication. IMessage uses the new message reminder system of iOS and Mac os, which can directly push information to the other party's screen, regardless of whether the other party is in the game or locked. If both parties are using iMessage, you can even see the state of each other's speech.
