Mine is an Apple mobile phone. How can a text message sent by my husband link someone else's mobile phone number?

This situation is because there are two mobile phone short messages available, and the solution steps are as follows:

1. Open iPhone and click Settings.

2. Click the "AppleID, iCloud" column at the top.

3. Click "iCloud" after entering the page.

4. Close the "Information" column of the iCloud page to solve this situation.
