1. How can I not be found in the telephone office or mobile business hall?

1. In order to better protect users' privacy, users' communication records and short message records cannot be checked casually. First, you must log in through the service password of the online business hall, and then the mobile phone must be in a normal state. The network hall will automatically send a random password to your mobile phone for authentication, and you can only query it if you enter it correctly, so you need two passwords, a service password and a random password.

2. Fetion is just a general chat tool, and neither the telecommunications bureau nor the business hall can inquire about it. If someone sends you a text message by fetion, and you reply by text message, you will be charged according to the SMS fee. You can check the other party's number in the net hall.

3. Sending messages by Fetion is free, except that chatting by Fetion is not cost-effective. It is recommended not to use it.

4. Records cannot be deleted. These are all user data saved by the third-party platform designated by the state. Even mobile communication data cannot be deleted by the mobile device itself.
