Is there any good way to identify fraudulent short messages, especially the mobile phone system of iOS?

Yes, you can identify it by installing a security software on your mobile phone. I usually use my mobile phone as a housekeeper, and I feel that it is very powerful for identifying this kind of fraud. When sending a scam message, the mobile phone housekeeper will automatically intercept it and then prompt that it is a dangerous scam message. Don't believe it easily, so you won't be cheated.
