I removed my phone number by accident when trying to turn it on how do i un-remove??

Hi PLSESHELPME,

If you can't see your phone number in iMessages and FaceTime, from your related article - Add or remove your phone number in Messages or FaceTime:

"If your phone number is unchecked and you can't select it, or you have some other issue, follow these steps:

2. On your iPhone, iPad, and iPod touch:

• Go to Settings > Messages > Send & Receive. Tap your Apple ID, then tap Sign Out.
• Go to Settings > FaceTime. Tap your Apple ID, then tap Sign Out.

3. On your iPhone:

• Go back to Settings > Messages and make sure that iMessage is turned on.
• Tap Send & Receive, then choose “Use your Apple ID for iMessage” and sign in with your Apple ID.

4. Using the same Apple ID, sign back in to Messages and FaceTime on your other devices."

Take care.
