If you spend more than the credit card limit, you can't brush it out. For example, if the credit line is 20,000, then you can only pay the consumption within 20,000, and you can't pay more than 1 minute. If you feel that the credit line is not enough, you can apply for a temporary credit line. Edit the last four digits of the short message CCTE# and card number # and the amount to be adjusted (if the original amount is 20,000, and now it needs to be increased by 3,000 yuan, then edit the last four digits of CCTE# and send it to the number 95533). Remember, if you want to send it with a bound mobile phone number, the approval result will be fed back immediately, which can take up to two months.
