How to automatically delete postal bank card information?

It is necessary to modify the mobile phone number and bank card at the counter of the savings bank of the province where the account is opened, and check with the savings bank of the province where the account is opened whether the business binding number is correct. If it is correct, please contact the operator to verify whether the short message is blocked. I suggest you log in to the personal online bank of Postal Savings Bank and bind your mobile phone number correctly. If it is correct, please try the transaction at another time. If it is not correct, I need to bring my ID card, bank card or passbook to the counter of Postal Savings Bank to modify the mobile phone number bound by personal online banking. If your account change SMS notification service can't receive SMS, please bring your ID card to the business hall.
