Who knows the cancellation method of postal SMS?

Hello, China Postal Savings Bank can take your ID card, bank card or passbook to the counter of Postal Savings Bank in the province where the account is opened to cancel the account. You can also edit the short message "QX" and send it to 1 1 185 to cancel the service; Some provinces and cities support calling local 1 1 185 to cancel; I hope my answer is helpful to you.
