If you are the one, the mobile phone receives the registration message.

If there is a registration, then go and have a look. Anyway, as long as the other party does not ask for transfer or remittance, there should be no loss, and at most it is a waste of time. But if you don't register, you must be a liar. Recently, there have been many fraudulent short messages pretending to be "Run Brothers" and "China New Voice". But "You Are the One" has not been heard for the time being. In short, if you don't sign up, ignore it.
