Can the secondary card be turned off by SMS?

I can't get it,

After the secondary card is closed, you can't receive messages, because you don't use this card anymore, so you can't receive any information from him. If you use the secondary card to bind the bank card, you need to unbind it in advance. Otherwise, if there is money in the bank card or there is any charge, you will not receive the information. Close the secondary card and apply for cancellation directly with your ID card in the business hall.
