I don't have an account for mobile traffic. Why do I get a message reminding me to use traffic?

It was the same before my mobile phone. Inexplicably, I played games with traffic on, which deducted me a lot of money. I looked this up later. There should be a virus in the mobile phone and some junk websites have been opened. The best way is for the human service to ask him to turn off all the flow switches, turn them off forcibly, and let him turn them on later. Everything was fine, and this never happened again.
