PART 1 Why doesn't iMessage Work?

iMessage is an instant messaging application that runs on iPhone and iPad devices. Therefore, the iMessage app itself, the Apple iMessage server, or the Settings on your device may cause it to not work properly. When your iMessage doesn't work, you can check in the above three directions. For example, if you can't communicate with all your contacts through iMessage, then you might want to check your device. Or if you can't connect with a particular contact via iMessage, the problem may be at the end of that contact.

Specifically, the common reasons why iMessage doesn't work are as follows:

1. Check whether the iMessage server works globally. When all users' iMessage applications are unavailable, server failures are more likely.

2. Your iPhone and iPad devices are not connected to a stable, fast Internet connection.

3. iMessage is not enabled in Settings on your iPhone and iPad.

4. Set the date and time correctly.
