What is it that I often receive verification codes from various softwares, and how to solve it?

Hello, it is very likely that someone else is using your mobile phone number to register the software, or that the software registered by a certain owner on this number has not changed the mobile phone number, resulting in the software verification code being sent to your mobile phone as soon as it is used. Another possibility is SMS bombing, but according to your description, the probability is low. In any case, please remember not to reply, never disclose the verification code, and download third-party security software to intercept it.
