Mobile phones have always been charged, but services that are not handled are charged. What happened?

You use an intelligent machine, right? And often download software online or something, right? Must have been targeted by rogue software. Most of these "rogue software" are included in some software you downloaded from unknown sources, and some even download and install it automatically when you browse some web pages. They automatically send text messages, mostly one or two. You can check your phone records. The solution is to format the phone after backing up the useful content in the phone. Hurry up before it's too late, or you'll get more and more deductions.
