What are the tips after being blacked out by Unicom?

Unicom's number will not be prompted when it is blacked out due to account cancellation due to number arrears, but it will be prompted when Unicom handles business, which will affect business handling.

Unicom blacklisted customers can't handle Unicom's post-payment, fixed-line users' access to the network, network transfer, and re-installation of sales numbers before canceling the blacklist.

Except for blacklisted customers who are suspected of short message fraud, fraud and other criminal acts determined by public security organs, blacklisted customers caused by other reasons can handle prepaid network access and transfer business.
