How does SMS show that the call is disconnected?

There may be, it may be downloaded software or it may be set by the mobile phone manager at home.

You can not only pause the service, but also set it to stop, close, unable to connect, and so on! However, it may also be the reason why the other party really does not pay for a long time.

The role of the blacklist:

In other words, if you don't want to answer someone's phone, you put him on the list. If you blacklist someone: When he (she) makes a phone call, your mobile phone will display "No XX" and then prompt that there is a missed call.

The caller will directly say, "The number you dialed is power off", "Sorry, the number you dialed is temporarily unavailable" and so on? . If you close it, then you are prompted to close it.

The blacklist is by phone. Can you send a message recently? You can receive a report of successful transmission.
