Huawei mobile phone * # function

This function has the functions of identifying the authenticity of mobile phones, querying usage records, and setting an empty number.

1. Identify the authenticity of the mobile phone: enter *#06# in the dialing interface, and the mobile phone will display the IMEI number, that is, the international mobile equipment identification code. This number is unique and can be used to verify the authenticity of the mobile phone.

2. Query usage records: enter *##6 130##* to view the usage records of mobile phones, including call records and SMS records. This is very helpful for understanding the use of mobile phones.

3. Set an empty number: By entering a specific code, you can set your mobile phone number as an empty number, so that when someone calls, you will hear the prompt "The number you dialed is empty". This function can protect the privacy and security of users in some cases.
