There is no credit card limit, which needs specific analysis, as follows:

1. The credit limit of the card is used up: repayment is made first, and the credit limit is restored in real time.

2. Freeze the credit line of overdue cards: repay first and then apply for unfreezing to restore their credit line.

3. Because there is no credit card limit: the credit card needs to be activated first. If there is still no credit limit, it may be because the cardholder applied for a quasi-credit card. In this case, the applicant needs to apply for a new credit card business at the issuing bank.
