If the SMS and WeChat chat records are deleted, how can I recover them?

If the short message is not backed up, it is generally unrecoverable after accidental deletion. If you are a Unicom user, Unicom has no right to inquire, because the content of short messages involves personal privacy. If you need to inquire about the details of SMS and MMS, you can log in to China Unicom APP, and click Service > Inquiry > Telephone Fee Business Inquiry > SMS and MMS Details on the homepage to inquire about the details of SMS and MMS within 6 months (SMS and MMS details only provide the records of the last 6 months).
