How to retrieve the SMS deleted by Charm Blue 5S

As long as you have a Flyme account and have synchronized it.

In the synchronized state, go to →Flyme webpage and log in to Flyme account-> Cloud service: Switch to the "Recycle Bin" group in SMS and post-it notes, retrieve the mistakenly deleted SMS and post-it notes, select them and click Restore.

The recycle bin will keep the deletion records of the last 6 months, and once it is emptied, it can never be recovered.

Note: the mobile phone contact suggests that you restore through the time machine function.
