2. Banks usually decide whether to unfreeze credit cards according to customers' repayment and credit records.

In this case, since all debts have been paid off, the bank may consider unfreezing the credit card, especially if your other repayment records are good.

4. However, the specific unfreezing result still depends on the credit card policy and the relevant regulations of CCB.

Extended data:

CCB's credit card has certain flexibility, so it is more likely to be unfrozen after all overdue payments are paid off. However, in practice, it is suggested to contact CCB staff in time to explain the overdue reasons and repayment willingness, so as to increase the possibility of unfreezing credit cards. In addition, the rational use of credit cards and timely repayment are also important factors to ensure the normal use of credit cards.
