Hello, the number you dialed is out of service. What happened?

This is to prove that the number you dialed, that is, the other party's number is not being used normally now. Abnormal use cases include arrears of downtime, registration of downtime, or participation in the use of contract machines and cards alone, resulting in default downtime.

Shutdown may have the following two situations:

1, really shut down

2. Add your number to the rejection number through some calling software, which is similar to the blacklist function.

Extended data

pay attention to

1. If the user only sets the interception call and does not set the interception short message, then the user who sent the short message from the other party can receive it;

2. If the user sets both interception of phone calls and interception of short messages, then the other party sends a short message to the user, and the user will not receive it at this time;

3. In addition, because the blacklist is only a local operation of the mobile phone, it will not be intercepted on the operator's server, so you just can't see the short messages in the inbox, and the mobile phone will still receive the short messages and phone calls from the other party. If you want to see the intercepted messages, you can find them in the interception record.
