The mobile phone deleted a short message by mistake. Can Unicom find out?

If it's the short message content saved on your mobile phone, Unicom can't find it. Because the content of short messages involves personal privacy. Unicom's SMS list can only find the number, time and cost of sending SMS. You can log in to the online business hall, and click on the phone bill inquiry > bill inquiry > short message and multimedia message detailed list to inquire about the short message and multimedia message detailed list in the last six months (including the current month).
