My Unicom SMS has been blacklisted. How to cancel it?

Users blacklisted by Unicom are generally due to the arrears of Unicom numbers registered with ID cards. It is suggested that you can take the owner's valid certificate to your Unicom business hall to cancel the blacklist by paying off the arrears. If in doubt, you can also consult the local customer service 100 10 or bring your ID card to the local business hall for details.
