The paper bill of China Merchants Bank's credit card cannot be cancelled by SMS for the time being. You can log in to the credit card online bank to modify the bill sending method, or you can directly call the customer service phone on the back of the card to access the manual customer service for acceptance.

The online banking modification method is as follows:

After logging in to the credit card website, click "Online Banking Login" on the right and enter the ID number, inquiry password and additional code. After logging in to online banking, you can find the current billing method in Account Management-Bill Sending Method Settings and modify it.

If you only accept electronic bills instead, you must remind:

1. Paper bills are no longer sent;

2. Electronic bills and paper bills have the same legal effect;

3. In case of default, paper bills will still be sent.
