What SMS does China Merchants Bank send to increase the credit limit?

Hello, the fixed amount is the maximum amount that we can recover. After this amount is used up, you can't overspend. If you need to continue to use your card for emergency expenses, you can apply for a temporary credit line from our bank, which can increase your credit line in a short time and let you fully enjoy the convenience brought by flexible credit line. Please call the customer service hotline of the credit card center at 8008205555 (free of charge, fixed telephone only) or 4008205555 (local call charge), and then press 1-4-9 to enter the manual service consultation or handling.
