SMS is not backed up.

If the short message is not backed up, it is generally unrecoverable after deletion. If you are a Unicom user, you need to check the details of SMS and MMS. After logging in to China Unicom APP, click Service > Query > Telephone Fee Business Query > SMS and MMS Details on the homepage to query the SMS and MMS details within 6 months.

Tips:

1. The above paths are subject to the information actually displayed on the query page.

2. The detailed list of SMS and MMS only provides the records of the last six months (including the current month).
