Will changing hands not remove the blacklist?

Change the blacklist of mobile phones and it will be gone.

Because all the data of the sim card are stored in the mobile phone, different mobile phones will have different data, so they will all disappear.

Card is an IC card held by mobile users of the global mobile communication system, which is called subscriber identity card. Global System for Mobile Communications identifies users through SIM cards. The same SIM card can be used on different mobile phones. The mobile phone can only be used in the network after inserting the SIM card.

The SIM card is the key for the mobile phone to connect to the mobile network. Once the SIM card is removed from the mobile phone, the mobile phone will not be able to enjoy all kinds of services provided by network operators except emergency calls. SIM card can not only be used as a key, but also provide a lot of convenience for users. Users only need to insert or embed the SIM card into any mobile communication terminal to realize communication. SIM card also manages a lot of information provided to users, which can be used to store short messages, especially those received when users are away or absent.
