What does imessage mean?

IMessage information is an instant messaging service that is sent to iOS devices or Mac devices through the Internet.

IMessage not only supports sending short messages, but also can send videos, pictures, location information and so on. IMessage information is different from ordinary short messages. It has super high security, and it is said that it is difficult for even the FBI to decrypt this information. Users only need the data support of WiFi or cellular data network to complete communication.

When both the sender and the receiver are in the network environment, the information sent is iMessage by default. If both parties have turned on the iMessage function, and one party is not in the WiFi environment and the signal is poor, the system will automatically switch to send SMS. After the message is sent, you can judge whether it is an iMessage or an ordinary short message by judging the color of the message. The blue message is iMessage, and the green message is ordinary SMS.

Matters needing attention in iMessage

First of all, there is a word limit for iMessage messages, and each message has a maximum of 2000 characters. If the word limit is exceeded, the message will be split into multiple messages to send.

Secondly, iMessage allows sending photos, videos, audio and other attachments, but the size of each attachment is limited. The maximum photo attachment is 20MB, and the maximum video and audio attachment is 100MB. If you try to send an attachment that exceeds the limit, it will fail.

In addition, iMessage does not allow sending blank messages or messages containing only spaces. If you try to send such a message, the system will not be able to send it. Therefore, when users send iMessage, they need to ensure that each message contains actual content and the format is correct.
