After I downloaded something and opened it, I closed it and did nothing. Within a few minutes, I received a message from 10086 saying: You have successfully ordered from China Mobile...

This is the bad thing about junk software. Once you click on it, it will send a customized text message.

Don’t worry about recovering the text message. Record the number and content of the text message. Call the 10086 manual and ask him to cancel it for you.

It’s almost the end of the month, so cancel as soon as possible, otherwise you’ll be charged again next month.

This is equivalent to you being charged 10 yuan this time.

Hope this helps.
