Send a short message with 189 mailbox, but there is something wrong with the short message verification code. What is the reason?

There are two verification codes for sending short messages. You need SMS verification code on the first day, and picture verification code after the second time. The SMS verification code will be sent to the customer's mobile phone and will not be displayed clearly. If the picture verification code can't be displayed, it may be that the browser is not compatible. You can suggest the customer to try another browser.
