Who knows how Unicom numbers can query the content of the short messages they have sent?

As the content of short messages involves personal privacy, Unicom has no right to inquire; If the mobile phone keeps the record of sending short messages, you can query the content of short messages directly on the mobile phone. Log in to the online business hall, and click on the phone bill query > bill query > short message and multimedia message list. You can query the short message and multimedia message list in the last six months (including the current month), but you can only see the sending time and number, but you can't see the content.
