The mobile phone received a strange message.

This can be judged as service information. If I'm not mistaken, I'll let you click on the link to surf the Internet. I suggest not to click easily and just ignore it.

In addition, when you turn on your mobile phone, there should be sub-items such as "service email" or "push message" in the "browser" option, and the information you received should be in it. You can turn it off directly through "Settings" in the browser, which is generally useless.
