Why did the message of flying pig reach my mobile phone?

Theft of information or promotion by businesses.

The short message you received was just stolen by others or a marketing tool of the merchant. Pay attention to privacy and safety when surfing the internet now. All kinds of apps must be carefully authorized. Our privacy is basically collected by these apps and then sold to this merchant, and we have become the object of phone text message harassment. This kind of privacy leakage will have a great impact on our life and work.
