Apple's 4s SMS has been deleted, can it be restored?

The SMS deleted from Apple's mobile phone cannot be recovered, but it can be found and seen.

The method is: there is a search bar on the main screen. Enter a word in the short message you are looking for, and you can find all the information of the word, including emails and short messages. As long as there is information about changing words, it will be displayed.

In addition, there is the so-called "Apple SMS recovery software" on the Internet, which may be used to "recover" short messages.
