What does it mean for vivo mobile phone to receive this text message?

You received a short message starting with #vivo#, which is an instruction message about finding a mobile phone. Because you have done relevant operations on the mobile phone website and your SIM card is installed in other brands of mobile phones, you will receive such a short 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.
