What is the content of the activation message?

Generally, you only need to get a verification code to activate it directly. Of course, it is very likely that many banks have different policies, so the activation methods are different. If you must send a short message, there should be a prompt about the content of the short message in the interface of mobile banking, or you can click the send verification short message button to jump directly, and then enter the short message page and click Send directly.
