The SMS numbers of Apple 12 are out of order.

If you open the backup address book in iCloud in advance, log in to iCloud official website, enter the settings, and click "Restore Address Book", a window will pop up listing the previously backed-up address books.

For example, your iPhone had an address book disorder on February 25th, 65438. You can choose to restore the address book that was backed up on February 24th or earlier.

Please note that if you add new contacts after the recovery date, they will no longer appear. For example, if you want to restore the backup address book on the 24th and add a new contact on the 25th, the new contact will not be kept.

Everyone must form the good habit of regular backup. Open the PC version of AISI Assistant, find "Backup/Recovery Data" on the "Toolbox" page, select "Address Book" in "Classified Backup" and save the phone address book on the computer.

If the iPhone address book is abnormal, select "classified recovery" on the same page, and select the backed-up file for recovery.

If the iPhone address book is disordered, you can refer to the above methods to solve it.
