How does Unicom check the phone bill, SMS and this month's bill?

You can log in to the homepage of online business hall with your mobile phone number, click "phone bill inquiry" > "detailed bill inquiry", and select the detailed bill to be inquired (such as phone 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). If you have any questions, you can also contact the Unicom customer service that the number belongs to for verification.
