The role of the blacklist of incoming calls

That is, you blacklist someone if you don't want to answer the phone.

If you blacklist someone, when he (she) calls your mobile phone, it will display "No XX", and then prompt that there is a missed call, and the caller id: "The phone you dialed is power off" or "Sorry, the phone you dialed can't be connected for the time being".

If you turn it off, then prompt to turn it off. Blacklists are for incoming phone messages.
