How to check whether it is blacklisted by Unicom?

1. If there is no Unicom number in use, you need to bring the original ID card to Unicom's own business hall for on-site inquiry.

You can look at the nearest Unicom business hall like this:

Open the mobile APP (login-free)-search for "nearby business hall" on the home page to enter.

2. If there is a normal Unicom number, you can check it online through your mobile phone.

The operation path is: log in to Unicom Mobile APP- Service-Query-Blacklist.

This query mainly supports the blacklist of accounts cancelled due to arrears of downtime. If there are other reasons, you still need to go to the business hall to inquire.

At present, the query only supports 4G users, and does not support 5G, 23G and mobile phone customers with number transfer.

How to remove the blacklist?

Under normal circumstances, many people will be automatically cancelled by the system because their mobile phone numbers are not in use, so the resulting blacklist will not need to go to the business hall, and the historical arrears will be paid directly through the mobile phone, and the blacklist will be automatically lifted after the arrears are paid.

Operation path 1: (login-free) The mobile phone opens the Unicom mobile APP.

Operation path 2: (login-free) The computer opens the Unicom net hall and clicks the payment-account cancellation number to make payment.
