Is there no SMS notification for CCB's car card?

Actually, I have already answered your last question. Please see "Best Answer Comments".

You must have received the statement sent to you by China Construction Bank.

At present, the billing date of China Construction Bank Longka Credit Card includes 7th,10th,12nd,15th,17th, 22nd, 25th and 27th of each month. We can ask the credit card center of China Construction Bank to adjust the billing date according to its own financial situation, but we can only adjust the billing date once within the validity period. Under normal circumstances, Longka credit card holders should repay the current bill within 20 days after the bill date at the latest. Therefore, the bill will not only indicate the customer's bill date, but also indicate the customer's (latest) due repayment date, and the cardholder must pay off the relevant funds before the due repayment date.
