Now go to the mobile business hall to make a phone bill. Can you find the content of the message?

If you register your name when you log in and bring your mobile phone and ID card to the business hall, you can print all the details of the past six months. During a call, you can view the calling party and the called party, only the messages sent and received, but not the content and text of the messages. If you don't have an ID card, you can use the service password, but you must bring your mobile phone!
