Will it prompt you if you are hacked?

Sending a message after a short message is hacked will not show anything in the past, nor will there be any hints. If the other party is blacked out in the short message, or the other party blacklists you, there will be no hint. Because it is the mobile phone system that is hacked, not the operator, the short message will not even display the number after being hacked. That is to say, if the mobile phone number is blacked out and blacklisted by others, the blacked-out number can send short messages to others normally and receive the prompt that the short message was sent successfully as usual. The harassment interception function only intercepts the other party's incoming calls or text messages, and will not prevent users from using them normally. Just because it is blacklisted on the mobile phone or other software, the message receiver will not show that it has received the message, but the message receiver can view it through the blacklist on the mobile phone or other software.
