If you need to activate your credit card after it is frozen, you have to call the bank's credit card service hotline to apply, and it needs to be re-approved. Credit cards are deactivated for many reasons, including risky transactions, cash-out behavior, long-term overdue payments, etc.

If the bank has frozen your credit card because it thinks there is a risk, you can call the customer service of the credit card center to inquire about the specific situation to see if you need to apply for a new card or you can open the card directly.

If it is because the bank determines that it is a arbitrage, then you not only need to explain clearly, but you may also have to go to the business outlet to submit relevant transaction certificates to prove that it is not a arbitrage.
