Can I still get messages from the other party when the apple is hacked?

Brand mobile phone has a black screen and can't receive messages from the other party.

Apple's "block this incoming number" function allows the other party to leave a voice message without receiving incoming calls, text messages and FaceTime, and the user will not be notified. The information sent or received will not be sent, and the contact person will not be informed that the phone call or information has been blocked.

The blocked mobile phone number can send a message to the other party, which will show that the message was sent successfully, but the message will be intercepted by the system in the blacklist message list, and the other party will not see the sent message.
