How to retrieve the previous SMS after Apple's mobile phone is restored?

After Apple's mobile phone is restored, you can choose to backup and restore the device from the iCloud cloud. The specific steps are as follows:

Turn on the device. You should see the "Hello" screen. If you have set up a device, you need to erase all its contents before you can restore it from the backup according to the following steps.

Follow the setup steps displayed on the screen until you get to the Applications and Data screen, and then tap Restore from iCloud Cloud Backup. ?

Sign in to iCloud with your Apple ID.

Select a backup. Check the date and size of each backup, and select the backup with the highest correlation. When a backup is selected, the transfer will begin. If there is news that you need a higher version of iOS, please follow the steps displayed on the screen to update (if you don't see the steps to help you update on the screen, please know what to do).

When prompted, log in to your Apple ID account to restore applications and purchase items (if you purchased iTunes or App Store content with multiple Apple IDs, you will be asked to log in to each Apple ID). If you forget your password, you can click "Skip this step" and log in later.

Stay connected and wait for the progress bar to appear and finish. Depending on the size of the backup and the network speed, it may take several minutes to an hour to complete the progress bar. If you disconnect Wi-Fi prematurely, the progress bar will pause until you reconnect.

You can now complete the setup and start using the device. Applications, photos, music and other information will continue to be restored in the background in the next few hours or days, depending on the amount of information. Always connect to Wi-Fi and turn on the power to complete the process.
