Why does my oppo phone receive the SMS verification code sent by vivo?

If you receive a message starting with #vivo#, it is an instruction message related to finding a mobile phone. It may be because you have done relevant operations on the mobile phone website and your SIM card is installed in other brands of mobile phones that you will receive this message. Vivo mobile phones will automatically hide this information, while other brands of mobile phones do not have this function, so they will display short messages.
