How to delete the detailed list of phones and mobile phone cards?

1. What you want to inquire should be the detailed records of calls and text messages. Because they are provided by the network operator, you can't delete them yourself. 2. If you don't want others to find out, there are two ways to query: 1) website query. After entering the query password in the telecom online business hall, you can query the user's own phone number, short message and online details. However, the owner can prohibit the inquiry of details through the online business hall, so that no one in the online business hall can find your phone records and only the owner can lift the ban. 2) You can go to the business hall with valid ID. This function cannot be blocked, but you need the owner to check it, and no one can do it for you. 3. Tip: The business hall needs an ID card to inquire about the detailed list, and various systems need passwords independently.
