If the credit card is frozen after the deadline, it can be unfrozen. In the process of using the credit card, if the credit card is frozen due to overdue, the user needs to repay in full, including the principal and overdue interest, and then call the hotline of the issuing bank to ask the customer service to unfreeze the credit card. In addition, users can also choose to unfreeze their credit cards at the bank counter with ID cards and other related materials after paying off the arrears.
