How to remove the blacklist of Unicom?

Users blacklisted by Unicom are generally due to the fact that the Unicom number registered by the user ID card is not in arrears, and users can cancel the blacklist by paying the arrears. Because the policies of different cities are different, it is recommended to consult the local manual customer service or business hall, and the local policies shall prevail.

Blacklist users include the following three types:

1, arrears of downtime for three months, including closed users and non-closed users.

2. Malicious users who owe money, such as users who maliciously defraud international information stations and users who maliciously defraud roaming charges in different places.

3, the public security organs to determine the suspected SMS fraud, fraud and other criminal acts of users.
