Why is the SMS recycle bin empty?

Short message storage time is set too short, and cloud synchronization function is not turned on.

1, the SMS save time setting is too short: in the mobile phone, you can set the SMS save time. Set the save time to be short, and only keep the messages in the last few days or hours. Old information will be automatically deleted and cannot be found in the recycle bin.

2. Cloud synchronization function is not enabled: If the cloud service is used, but the synchronization function of mobile phone related data is not enabled, when one or more pieces of information in the local storage are deleted, the corresponding operation will not be performed in the cloud, and the deleted information will not be found in the recycle bin.
