If you encounter the message “This number is registered to your Apple ID but is not associated with this phone” in iMessage or FaceTime, your iPhone may not have correctly registered your new or transferred phone number.

Possible Cause

After setting up a new Cape number or transferring from another carrier, your iPhone might not update the number in its settings, causing a mismatch.

Steps to Fix the Issue

Check and Update Your Phone Number in Settings

Go to Settings → Phone → My Number.
Ensure your Cape number is displayed.
If blank or incorrect, tap My Number and enter your Cape number, including the country code. Tap Save and go back.
Example: Enter +11234567890 (with +1 as the U.S. country code).
Restart your iPhone after updating.

Ensure Your Number Is Listed in iMessage and FaceTime

For iMessage: Go to Settings → Messages → Send & Receive.
- Ensure your Cape number is listed and selected.
For FaceTime: Go to Settings → FaceTime.
- Verify your Cape number is listed and selected.

Turn iMessage and FaceTime Off and On

Go to Settings → Messages and turn off iMessage.
Go to Settings → FaceTime and turn off FaceTime.
Restart your iPhone.
After restarting, turn both iMessage and FaceTime back on.

Sign Out and Back into Your Apple ID

Go to Settings → Tap your name at the top → Sign Out.
Follow prompts to sign out, then sign back in with your Apple ID.

Reset Network Settings

If the issue persists, reset your network settings.
Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
Follow the prompts (Note: This will reset Wi-Fi networks and passwords, so save them beforehand).
