Can I cancel the postal SMS service by sending Qx to 11185?

Hello, for the Postal Savings Bank of China’s current account change SMS notification service, you can bring your ID card, bank card or passbook to the Postal Savings Bank counter in the province where the account is opened to handle the cancellation; you can also use the mobile phone that receives the SMS. Edit the text message QX (not case sensitive) and send it to 11185 (sent between 9:00 and 16:00) to cancel the service; I hope my answer will be helpful to you.
