How does Apple iPhone7 recover the deleted SMS content?

I just recovered successfully, and I'll tell you the recovery steps.

1. First, you need to download iTunes software on your computer, connect your mobile phone to your computer, and back up your mobile phone data with iTunes.

2. After the backup is completed, open Mutual Shield Apple SMS recovery software, select "Restore from iTunes backup file", find the backup file just now, and scan it.

3. After scanning the software, select "SMS" on the left side of the interface to find the SMS we need to recover, check it and click Export in the lower right corner to complete the recovery.
