Where can I find records of phone calls and text messages?

Of course, you can find it in the business hall or on the website.

The way not to be found is to look at the mobile phone and don't let others know the login password of the Internet.

Because checking the system in the business hall will send a temporary password to the mobile phone, so the mobile phone holds it itself.

You know your login password, because with your login password, you can read your SMS records online.
