the increase of the credit limit has nothing to do with the points, mainly depending on the usual situation of using the card and repayment. You can choose different physical store merchants to use the card and repay in full. After using the card for a period of time, the bank will actively adjust the permanent credit limit. If there is any adjustment, the bank will invite SMS, but the landlord should also be careful. There are many fraudulent SMS messages, which specifically defraud customers' information. There will be a fixed phone number in the SMS to ask you to call back. Never call back. After receiving the message, you can reply this message to 95533 to verify the authenticity of the message.
