I query visited a mobile company, and I didn't order any services, but how did the service fee on my mobile phone come from?

If you're sure you haven't used it, call the manual desk 10086 to complain and ask the operator to record the feedback for you. The operator will ask you if you have confirmed that you have not ordered, whether you have received the SMS reminder of charging, and also ask you the model of your mobile phone (there are often some charging traps in the cottage). Just tell the truth, and he will feed you back to the relevant departments, where you can see your detailed usage. There is no need to go to the business hall. There is no manual desk in the business hall. The artificial desk is bigger than the business hall, and the service attitude is still very good. In addition, I think China Mobile has done a good job in charge deduction. It is very safe to call 10086. I was once denied access to the Internet 18 yuan, but actually I should have used 3 yuan more, so I complained. I checked there, and I was really charged the wrong fee.

And you don't have to worry about whether it's a mobile phone, because some mobile phones have traps, and if you don't use them, you will be charged, but as long as you haven't subscribed to these services, you can ask Mobile to refund your fees.
