Why do I need a verification code to check the call records?

If you need to check the call records, you can find out the relevant information by checking the call details. You can log in to the online business hall/home page with your mobile phone number, click call query > bill query > detail query, and select the details to be queried (such as call details, SMS MMS details, value-added services details, Internet traffic details, WLAN details, etc.). ) to inquire about your situation in the last six months (including the current month). In order to ensure the safety of users' information, the detailed list query function adds SMS secondary verification, that is, when users log in to the online business hall to query the detailed list, they need to enter the random verification code twice to query the user's detailed list. If you have any questions, you can also contact the Unicom customer service that the number belongs to for verification.
