PHS short message list

If it is a PHS in Beijing, as long as the information in your PHS mobile phone is deleted, even if your mother wants to check it, she must have a master certificate, and she needs to bring her ID card to the business hall to print the list (if it is a PHS with a monthly subscription, she can't type the list), but the list only shows the number sent, the total number sent, the time sent and the corresponding fee, and the content will not be displayed. Your phone records, number and time will be on the list.
