When your fixed quota is not enough to pay the related expenses, you can try to apply for a temporary quota. Temporary lines can be used immediately after they are successfully upgraded. The temporary line used (exceeding the fixed line) does not enjoy the convenience of circulating credit, and must be paid off in one lump sum on the due repayment date. The specific repayment amount is subject to the bill. If the account is not paid off on time, interest will still be charged. There will be no over-limit fee for using the temporary quota, and there will be no handling fee for applying for an increase in the temporary quota; Applying for a temporary quota requires bank evaluation, and the results may be inconsistent every time.
