How to query call records and short messages in Unicom's online business hall?

You can log in to the online business hall/click on the phone bill query > bill query > detailed bill query > bill list, and you can query the details of the bill list in the last six months (including the current month). The content of SMS can only be queried in your own mobile phone. If the message has been deleted, it cannot be queried. The short message list in the online business hall only records when you sent the short message to what number, and the content of the short message is not recorded, so you can't query your short message.
