Only the card number can be used to find out whether the secondary card has a SMS reminder?

Hello, you can't. The main card and the secondary card only enjoy the flow of the package, and cannot query and receive the information of the secondary card. However, the main card can check the payment status in the online business hall and handheld business hall. Both the main card and the auxiliary card can handle emergency shutdown, but they can't handle shutdown and registration number, and they can't handle network transfer. If you need to transfer, please leave home and the card before you apply.
