There is a reason for the low credit card limit, which is the result of the comprehensive evaluation of the applicant's qualification by the bank credit card center and cannot be improved in the short term. If you think this card is low, cancel it and then apply for a credit card at this bank or other banks, you may be rejected. It is suggested to use this credit card more, repay the credit card bill on time and apply for installment appropriately, which will gradually increase the credit limit of the credit card.
