How does Unicom view the deleted SMS records?

1. If you are inquiring about the detailed list of Unicom numbers and short messages, you can log in to the online business hall and mobile business hall through your mobile phone number and service password to inquire about the number records of sending short messages within half a year (including the current month), but you cannot inquire about the detailed list records of receiving short messages. 2. You can query the short message list in the following ways: (1) Log in to the online business hall, click Call Query-Details Query, and select Query-Details Query of Short MMS to query. (2) Log in to the customer service terminal of the mobile phone business hall, and click "Service"-"Inquiry"-"Detailed List of SMS and MMS" to inquire.
