I don't have postal savings card, but I got a message today about how much money is in my account card and the balance.

Hello, the question you submitted may be that when the Postal Savings Bank handled the SMS notification service of current account change, someone else mistakenly wrote the wrong mobile phone number and wrote it for you. If you really haven't opened the SMS notification service for current account change and account change at the Postal Savings Bank, then you don't need to pay attention to this SMS. Customers who need to notify account changes by SMS will go to the counter to check and modify their mobile phone numbers without receiving SMS.
