Temporary credit line, as its name implies, refers to the credit line temporarily adjusted by the bank to credit card holders. Generally speaking, temporary credit lines are all increased. When the fixed credit limit of your credit card is not enough (such as decoration, travel, etc. ), you can call the credit card center of the issuing bank and ask the customer service to temporarily increase the credit limit within a certain period of time. The customer service will determine whether the credit limit can be temporarily increased for you according to your card use record, and the credit limit will be transferred back to the original fixed limit after the specified time.
