Can you go to the mobile business hall and type the messages you send and receive?

No, the short message content can't be typed without this service, which belongs to privacy. Mobile will not be saved, only the record of sending SMS will be saved. You can print and send bill records, telephone records, etc. Use your password in the business hall, but your short message and telephone content can't be provided unless it is related to the case. Interpol must provide corresponding certificates, otherwise it is illegal to peek at the contents of short messages and phone records.
