If it is hacked, will it show that it has been delivered?

If it is blacked out, it will also show that it has been shipped. Take SMS as an example. A black screen can also show that the message has been delivered. After the other party pulls himself into the blacklist, the SMS content will be automatically pulled into the SMS content part of the blacklist, and no SMS reminder will be given. The other party will cancel the blocking process or blacklist the message content. Therefore, if you want to determine whether it is hacked by the other party, you can try to dial the other party's phone with a public phone or other mobile phone number. If you can connect, it means that your mobile phone number may have been hacked by the other party. In addition, due to the different SMS platforms at home and abroad and different processing methods, it may also affect the display of SMS sending status. In addition, in some communication applications, messages can still be sent after being hacked, but the other party may not receive message reminders, depending on the application used.
