Why do you always get yellow messages?

It may be a virus, or it may be that the mobile phone number is leaked.

In the process of downloading software, mobile phones will also download Trojans and viruses, especially if they download software from unknown websites instead of official download centers, it will easily lead to Trojan virus, which will lead to the leakage of mobile phone numbers and often lead to yellow spam messages.

You can use the mobile phone housekeeper that comes with your mobile phone to clean the virus, or you can go to the app store that comes with your mobile phone to download the official mobile phone security software, and then clean the virus.
