Why do you receive text messages as soon as there is consumption in the CCB account?

SMS reminder service is definitely available, but do you handle it differently? For example, I send you a text message saying it's free. If I don't cancel after one month, I will use it by default. Mine is the same. I didn't handle it myself, but I still received a SMS reminder. This money was directly deducted from my card, not from my mobile phone fee.
