If your credit card is frozen, it means that you have not overdue once. For security reasons, the bank temporarily froze your credit card. If the loan is repaid, the frozen credit card will rarely be unfrozen.
But if you want to unfreeze, you can take the initiative to negotiate with the bank, and remember that the attitude must be good. After paying off the debt and communicating with the bank, you still have hope to continue to use the card.
