Why does my mobile phone always receive some inexplicable charging information?

Is your card handled with your own ID card? If it's a black card, you don't have to go to the business hall. If it is your ID card, you can go to the business hall and ask the staff to check it for you. My mobile phone also has the phenomenon of arbitrary deduction. Sometimes they will call you and ask what you have subscribed to, and then you say no, and he will deduct it for you. There is also the modification of the initial password of the mobile phone.
