How does iphone5 back up SMS?

Open itools, connect iphone, and click "Information Management"-"SMS".

Click "Backup" (at the red line), and a dialog box for modifying the name of "Backup SMS" will pop up. The default value is date and time.

After the backup is completed, you can click "Open Backup" several times to view your backup, and select one of them, and the itools SMS interface will return to the SMS backed up that day.

After backup, you can also export CSV format and open it in excel.

In addition, it also supports deleting short messages online.

Finally, synchronize the backup you want to restore, or the edited SMS to the device, and you can restore it to the iphone.
