Received a short message from China Merchants Bank. Is it okay to reply and unsubscribe?

In general, there is no problem. However, it is not recommended to reply directly in the future, for fear of being used by criminals. If you really want to return some business, you can go directly to the bank. It's a little troublesome, but it's more reliable. Bring my ID card and bank card to the bank counter to submit an application for cancellation of service. You need to provide your ID card and bank card, which will take effect after the counter is successfully handled;

Log in to online banking personal online banking, and in the account security management menu, select Close SMS reminder service; (Prerequisite: Online banking bank card account has been opened)

Call the bank customer service and ask the customer service staff to turn off the SMS reminder service after the manual service has passed the certification. (Prerequisite: the bank card account of telephone banking has been opened).

All three methods can be used.
