What will the text message show when Apple is blacked out?

As soon as the phone is unplugged, the other party will show that the message has been delivered.

If the other party blacked himself out, there will still be a prompt of successful sending, but the receiver will not have any acceptance prompt. At this point, if you haven't seen the word "read" next to the bubble on the text message for a long time, you can be sure that it has been blacked out by the other party.

Apple has the function of sending text, photos and videos between devices for free, which is different from the traditional SMS service. When someone adds a phone number or apple to their contact list, they can send a message.
