Postal savings card has no money. Will the SMS service continue?

Hello, if you don't cancel the SMS notification service of current account change, you will be charged all the time; If you are not going to continue using this account, it is recommended that you bring your ID card and bank card (passbook is required if you have a passbook) to the counter of the Postal Savings Bank in the province (county, city) where the account is opened to cancel the SMS notification service, and then cancel the account; I hope my answer is helpful to you.
