Credit cards not only have a credit limit, but also have a consumption limit function. That is, when a credit card is swiped for consumption, there is a single consumption limit. It does not mean that the amount of credit can be spent at one time. If your credit card is limited and cannot be used, you can contact the bank's customer service and ask the customer service why your credit card is limited. For example, if it is because of overdue debts, pay off the debt as soon as possible; if the bank suspects you of cashing out, you can see if you have made any large purchases recently, and then explain it clearly to the bank.
