Reconnect after a recipient changes phone numbers

Separate the changes

• Whether the person changed only their number or also their Apple Account.
• Whether the existing connection still shows accepted access.
• Which number a new Messages invitation would actually use.
• Whether a fresh check-in still appears on their current phone.

Replace the setup only when needed

1. Confirm the new number through an existing trusted conversation.
2. Update the phone’s contact details.
3. Review the person’s status in DailyCheck and test existing delivery.
4. If the stored setup needs replacing, stop the old access and confirm the result before removing the person.
5. Add the correct person, send the new invitation to the reviewed address, and test after acceptance.

An address and an account are different

A phone number helps address Messages. Apple’s private share has its own access state. Do not interpret a number change as proof of revocation or guarantee that the previous connection disappeared.
