After six months' successful application for credit card use, the holders of Guangfa Credit Card can apply to the bank to increase the credit card limit. Of course, not everyone who uses the credit card of Guangfa Bank can increase the credit line smoothly after half a year. If you want to increase the quota, you still need to use more credit cards. For example, in our daily life, we often use the credit card of Guangfa Bank to swipe our cards, but we can't brush all the quotas. Second, timely repayment, leaving a good credit record, is conducive to increasing the amount. There is also the possibility of regular installment payment and so on.
