Add the number of the other party to the blacklist. Does the other party know? Can I get through by adding the other party's number to the blacklist?

When you add a number to the blacklist, the mobile phone system will automatically intercept the incoming calls and text messages of the number, and the other party will not receive any tips or notifications. Therefore, the other party will not know that you have blacklisted their numbers.

Once you add a number to the blacklist, you will not be able to connect to your mobile phone from that number. When the other party calls you, they will hear a busy tone or a prompt tone, telling them that the phone cannot be connected. Similarly, you can't receive text messages from this number.

The specific method of adding the number to the blacklist may vary according to the brand and operating system of the mobile phone. Generally speaking, you can set the blacklist through the settings menu or call records of your mobile phone. On some mobile phones, you can also use third-party applications to manage blacklists.

The blacklist function is usually very flexible, and you can add or delete numbers at any time. If you add a number to the blacklist by mistake, or you want to contact someone again, you can easily delete their number from the blacklist. Similarly, if you find that a certain number often bothers you or sends spam messages, you can always blacklist their numbers and block their contact.

Suppose you often receive harassing calls and text messages from a strange number, you can blacklist this number. Once you blacklist this number, you will no longer receive calls and text messages from this number. If the other party tries to call you, they will hear a prompt and tell them that the phone can't be connected. Similarly, you can't receive text messages from this number.
