Text messages often receive yellow text messages. Why?

Because it is allowed to open the phone. I always receive pornographic short messages with provocative language and a web page link, which is caused by users registering an APP to allow them to open their mobile phones. The risk of fraud is high. "Never click or reply", you can use the mobile phone housekeeper that comes with your mobile phone to clean up the virus, or you can go to the app store that comes with your mobile phone to download the official mobile phone security software.
