How to judge whether the number is blacked out or not?

You can try texting. If you don't call someone to ask if you are blacklisted, send a text message. If you are blacklisted, you usually can't send text messages.

But there is another possibility, that is, the other party only accepts white list information. No matter whether the other party blacklists your phone number or not, the other party can't get through, but this possibility is very low.

Extended data:

When the phone is hacked, the following situations will occur when calling the other party:

1. The number you dialed does not exist.

The number you dialed is temporarily unavailable or busy.

Sorry, the number you dialed is busy, please redial later.

The number was hacked by someone else. In fact, the other party used the call firewall, call guard, call do not disturb and other functions on his mobile phone.

The principle of this function is that when a call comes in, the mobile phone simulates the user to operate the hang-up key to quickly hang up the phone. The phone will not display the interface of incoming calls, but will display the icon of missed calls at the top of the phone screen, and automatically save the incoming number in the missed calls in the call record.

If the other party sets this function, he will listen carefully to the dialing prompt, hear a short beep, and then the voice prompt.
