phone number
i accidentally changed my phone number in the phone settings thinking it would do nothing but now none of my messages will send and they're all green even after i changed it back to the old number. any idea how to fix this?
iPhone 8
Deregister the phone number you're not using anylonger:--> Deregister and Turn Off iMessage - Apple Support
If the issue still persists, contact Apple Support and explain your problem, using this link:--> Get Support
