iMessage can not connect my phone number

Thanks for reaching out 芸瑄,

It sounds like you're having some difficulty updating your phone number with Messages. We can help.

You can start with this steps to Add or remove your phone number in Messages or FaceTime:

Set up your phone number

On your iPhone:

1. Go to Settings > Messages and make sure that iMessage is on. You might need to wait a moment for it to activate.

2. Tap Send & Receive. If you see "Use your Apple ID for iMessage," tap it and sign in with the same Apple ID that you use on your Mac, iPad, and iPod touch.

3. In the "You can receive iMessages to and Reply From" section, make sure that your phone number and Apple ID are selected.

4. Go to Settings > FaceTime and make sure that your phone number and Apple ID are selected in the "You can be reached by FaceTime at" section.

On your other devices, you can now turn on the phone number that you just set up:

* Turn on your phone number for your Mac

* Turn on your phone number for your iPad or iPod touch

Hope that helps.

Take care.
