What does SMS verification code mean? Who can help me?

It is a service bound to mobile phone, and operators use it to protect customers' secrets from being stolen. For example, if you want to check the phone bill in the mobile online business hall, it will send you a short message verification code. You can only check the phone bill by inputting the short message verification code sent to your mobile phone into the designated position on the computer screen. This is the function of SMS verification code. If you don't have a mobile phone, you certainly don't have a SMS verification code, so you can't view the information you want.
