Hello, this card friend. Under normal circumstances, the bank will adjust the credit limit of your credit card from time to time according to your consumption situation, and when your credit card has been used for more than six months, you can also take the initiative to apply to the bank to increase the credit limit. However, if your credit card has been used for one year and the credit limit has not been increased, it may be that you don't use it enough at ordinary times. You should always use credit cards, swipe more cards and brush as many large bills as possible, so that the bank will think that your credit limit is not enough and will increase your credit limit. But the premise is to ensure good card habits and timely repayment, and there can be no overdue.
