Does the other party know after the SMS blacked out the other party?

According to the query, Wikipedia's website shows that the other party who hacked the text message can't see it, but can receive the text message. After receiving the short message, there will be no prompt, and it will not be displayed on the normal short message interface of the mobile phone. Because the other party has blacklisted his number, the mobile phone will intercept the incoming calls and text messages of the blacklisted number, but interception and rejection are two different things. What is certain is that the other party will receive the message.

Black-out refers to black-out in network language. Blacklist, no more contact. Generally speaking, it is a blacklist to block someone's speech. As a fashion expression, it can be extended to the emotional rejection of an event in real life and someone who will be separated forever.
