Why doesn't my CCB credit card charge SMS reminder fee? I didn't see the deduction. I also send messages below 500 yuan.

If the transaction amount of the landlord is greater than or equal to 500 yuan or overseas, there is a default SMS reminder service. 3 yuan will be charged every month after the opening of small transaction SMS, and every transaction will be reminded by SMS regardless of the amount. This fee will be deducted on the date of each bill, and the landlord can pay attention to the details of the bill.
