I mistakenly de-registered the wrong phone number. It was my real one. How do I undo this??
iPhone 12, iOS 14
Deregistered it where?
If with your network operator then get in touch with them quickly. Neither we nor Apple can help.
If a trusted number in appleid.apple.com security then add it back.
Or where?
