Can the main card of Unicom's 4G primary and secondary cards see the detailed list of secondary cards?

Unicom's main card cannot query the details of the secondary card. You can log in to "bill inquiry" > "bill details inquiry" in the online business hall with the mobile phone number and service password of the secondary card, and select the bill details to be inquired (such as telephone bill, SMS and MMS bill, value-added service bill, Internet traffic bill, WLAN bill, etc.). ) Inquire about your detailed bill for 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.
