Why can't I find the deleted SMS in Xiaomi SMS Recycle Bin?

The SMS recycle bin is not opened, and the application permission is limited.

1, SMS recycle bin is not turned on: For some newly bought Xiaomi phones, SMS recycle bin may not be turned on by default. You need to delete a short message in the short message list, so that it will be deleted directly without entering the recycle bin. You need to turn on the SMS recycle bin function in the settings interface to get back the mistakenly deleted SMS.

2. Limited application authority: Some system applications or applications requiring special authority may not be switched through application management. The on-off status of these applications is automatically managed by the system and cannot be modified manually.
