How do I fix iMessage not working on my iPhone?

You have not provided enough information to know why it is not working.

• Is it an Activation error. If you can’t turn on or sign in to iMessage or FaceTime on your iPhone - Apple Support
• Or did you receive a block due to sending messages that were repeatedly reported as Spam? In this case you would usually get an email from Apple to the email address of your Apple Account and the block may be temporary or permanent. In that case contacting Apple directly would be needed if there is any possibility to remove the block. Contact Apple Support - Apple Support
• Is this a Screen Time restrictions where a parent/guardian has restricted communications?
• Or is is something else entirely.
