I withdraw money from my bank card. Why is the message sent to my father's mobile phone?

There is SMS notification service when the bank opens the card. When your withdrawal amount exceeds this amount (for example, 100 yuan), the SMS will be sent to the mobile phone bound to your bank card. At present, the mobile phone bound to your card belongs to your father. Because the bank card needs to check the ID card, and the mobile phone number is another additional service, you don't need to check the ID card, so you can fill it in at will. In addition, if you want to change your mobile phone number to your own, you can take your ID card to the bank when you apply for a card. After entering the bank, first go to the consulting place to find the account manager and show your purpose!
