Credit cards cannot be canceled on mobile phones.

1. Credit cards cannot be canceled on mobile phones, only through manual customer service. Users can call the customer service number, switch to manual customer service and make relevant applications to log out directly. To give a simple example, if a China Merchants Bank credit card user wants to cancel their credit card at this stage, they need to call the customer service hotline. When making an application, the user needs to provide their ID number, the unit filled in during the application, telephone number and other information. The purpose of doing this is to confirm your identity. Of course, each bank has different requirements for canceling credit card services. You can follow the customer service requirements.

2. If the application fails to pass the review, the credit card application is rejected, and there is no need to cancel the application. Before applying for a credit card, users must consider whether they need to use a credit card.
