What is imessage?

IMessage is an instant messaging software released by Apple WWDC20 1 1, which is built into iOS5 and Mac os x 10.8. You can send text, pictures, videos, address books and location information between iOS and Mac os devices, and support multi-person chat. 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 to 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.

Short message status

IMessage can tell you whether the message has been delivered, and if the receiver has enabled the read receipt, you can also see the read receipt message of the message. When someone is replying, iMessage can also display status information so that you can continue the conversation naturally and smoothly. When the text bubble is blue instead of green, you will know that you are using iMessage instead of SMS, and you will receive a reply faster.
