Can China Unicom’s online business hall check text messages and record messages?

You can check the details of SMS and MMS details in the past six months (including the current month) by logging into the online business hall/clicking Bill Inquiry>Bill Inquiry>SMS and MMS Details. However, the content of the text message cannot be queried. Since the content of the text message involves personal privacy, China Unicom has no right to query it. If your mobile phone retains a record of sending text messages, you can directly query the content of the text message on your mobile phone.
