How to restore the deleted SMS content?

Accidentally deleted messages can be recovered by software:

Stop reading and writing any data on your mobile phone immediately after you decide to resume the deleted SMS. This is because saving deleted SMS depends on whether the storage space has been overwritten by other data, so once you decide to resume SMS, don't do any other data reading and writing operations.

Download the Android recovery application on your computer. Direct Baidu "SMS Recovery" can find many similar software.

After downloading the SMS recovery software, connect the mobile phone to the computer and enable USB debugging of the mobile phone. Set it up, then find an application or developer tool, and find USB debugging. Click to enable this feature to connect your phone to your computer.

Open the Android data recovery program and click the "Start" or "Scan" button. You can use the software to search the data on the Android phone and find the deleted messages in the "Messages" section.

If it is found, click the deleted text. Click the "Restore files to your phone" option. Wait for the recovery process to complete. If you don't see the short message on your mobile phone, you can record the relevant information by hand when the data recovery program on your computer is displayed.
