Do I need to receive a notice to intercept mail?

You don't need to be informed. First, you can't see. The other party's mobile phone can receive the short message you sent. Because it was intercepted, you won't see this message in your message list.

Second, we can see that some Android phones will display interception reminders when receiving short messages with blacklisted mobile phone numbers: when receiving short messages with hacked mobile phone numbers, the notification bar will display that the short messages have been intercepted. At this time, click Intercept SMS to enter the SMS application interface, and directly open the Intercept SMS to view the content;

Therefore, whether the mobile phone number is hacked by the other party can be successfully sent, but the first one can be seen by the other party at the first time. In the second case, a short message can actually be received. How to view it: Click on the short message in the mobile phone, and then click the information setting option at the bottom to see the short message sent by the black number.

So what prompt will we hear when the phone is hacked? Generally, when we dial the other party's phone, we will immediately hear a rapid beep (1-2 seconds), which may be because the other party's mobile phone is faulty or the signal is too weak. If we hear a hurried beep after 6 seconds, most of the time it is blacked out by the other party. At this time, we will teach you a very effective method to judge whether the other party blacked you out and forced the other party to connect. You just need to download an app called Cloud Dial Phone or Touch Call VoIP in the mobile phone application market. These softwares have the functions of preventing hacking and connecting hacked phones, and encrypting and hiding outgoing numbers, that is, the other party's mobile phone displays a virtual strange number, which is usually used to protect the privacy of the calling number. If you can get through, your phone has been hacked. If you still can't get through, it must be because the other party's mobile phone is out of service, turned off or faulty.
