Will the text message show that it has been delivered when the phone is black?

When the mobile phone is hacked, the text message will show that it has been delivered. Send text messages after being blacked out by the other party. In the past, my mobile phone would receive a prompt that the SMS was successfully sent, and the other mobile phone would intercept the SMS. Because hacking is the behavior of the mobile phone system, not the behavior of the operator, there is no hint when setting the number to send a message in the future. If your number is hacked by someone else, you can still send a short message to the other party normally, and you will also receive a prompt that the short message was sent successfully, but the other party's mobile phone will not show that you have received your short message.
