Increasing the credit card limit depends on the individual's spending power, not to say that as long as you spend, you will increase the limit.

Banks generally review your spending power regularly. If your credit card spending often reaches the limit for a period of time and the repayment is timely, then the bank will take the initiative to increase your credit limit next year.

If you want to increase the credit limit now, you can directly call for an increase or a temporary increase.
