The phone was intercepted. Can the sender see it?

The mobile phone was intercepted and the sender could not see it.

SMS Interception Settings. If the other party sends a message with a delivery report, then after you intercept it, his mobile phone will receive a short message, indicating that the message was not sent successfully. In this way, the other party will know. If the other party's information settings have not received the delivery report, then the other party will not know your information after it is intercepted. Only you can't receive his message, because it has been blacklisted. If you need to see it, you have to open the blacklist SMS record to see it!
