How do you know that the other party's text message has blacked you out?

You can measure it by phone, but you can't measure it by text message.

After the other party blackmails you, whether it is a phone call or a text message, the other party can't accept it. Call the other party, if the display is always busy, on the phone, turn off the phone, and change it several times. It's usually blackened.

If you want to check, you can borrow another phone number to call him. If someone else can get through, you can't get through, and you will definitely be blacklisted.

Extended data:

The contents of the call prompt on the phone blacklist are:

1. If you hear that the subscriber you dialed is busy, it means that the other party has set your phone to hang up automatically.

2. If you are prompted that the subscriber you dialed is turned off, it means that the other party has set your mobile phone number to transfer to another public mobile phone number in the black system.

3. If the number you are prompted to dial is not in service area, it means that the other party has set your mobile phone number to transfer to WeChat official account, which is not in service area.

4. If the number you are prompted to dial does not exist, it means that the other party has set your mobile phone number to be transferred to WeChat official account without an existing number.
