I have a CCB Dragon Card (deposit card). Every time my family transfers money to me or I withdraw money, there are text message reminders. Why are there no text message reminders during this period?

Well, in fact, many people have encountered this problem. Sometimes it is due to problems with China Telecom, China Mobile, and China Unicom. There are also bank backend systems that are busy and under maintenance. Let me give you a suggestion. Go to your local retail outlet and ask if it is due to the backend and if so, when it will be restored.
