no! There will be no charge for raising the quota. However, you don't need to apply for the fixed credit line of CCB. The bank will review your comprehensive situation (such as credit card use, repayment, credit standing, etc.) and take the initiative to improve it from time to time. However, if it is urgent and the fixed credit line has not been improved, you can adjust the temporary credit line, edit the application amount in the last four digits of the CCTE# card number by SMS and send it to 95533. It is very convenient to feedback the approval result immediately (for example, the original credit line is 5K, and now, CCB's control over the quota increase is still relatively strict. Whether it can be improved depends on your credit card. The landlord usually spends more on credit cards and repays on time. With a good credit card record and repayment record, the bank will naturally help you improve.
