What happened? Blacklisted for no reason, said that he owed money and didn't charge the phone bill.

Blacklist users include the following three types:

1. Arrears for three months of downtime include cancelled users and non-cancelled users.

2. Malicious arrears users, such as users who maliciously defraud international information stations and users who maliciously defraud international roaming charges.

3. Users suspected of short message fraud, fraud and other criminal acts identified by public security organs.

Users blacklisted by our company are generally due to the arrears of Unicom numbers registered with ID cards. You can bring valid documents to the Unicom's own business hall where the number belongs to pay the arrears and cancel the blacklist. If in doubt, you can also consult 100 10 manual customer service or bring your ID card to the business hall for details.
