Why does my mobile phone receive "The mobile phone number that sent this message is using your mobile phone, please pay attention!"

1, you sent this short message to yourself, you asked someone else's mobile phone to send this short message to you, you wrote this short message on the new message \ memo \ clipboard \ mobile phone screen, you got a virus in your mobile phone, you hallucinated, the first one must be right, your mobile phone was struck by lightning, and you were struck by lightning.
