GSM Box with Invisible Spy Earpiece

GSM Box with sensitive Microphone

You can establish with the person who will help you and dictate your answers, a series of signs. For example, if your home help dictates your answers and you fall behind with writing or if you do not understand a word you can pretend you scratch in the area where you have the GSM Box and knock in the box, your home help will hear and will repeat the last words or the last sentence. A performant microphone will help the home help who dictates the answers to hear louder and clearer what is happening in the exam room.

The sound quality in the mini spy Earpiece in the ear is very good. A very important feature of this device is the automatic response function, more precisely when someone calls the SIM number in the device, the box will respond automatically without having to press any buttons.

All of these features make this device one of the best systems for cheating on exams, guaranteeing 100% safety.

The system consists of:

  • The GSM Box: It’s a special micro-telephone that makes direct connection between the home help that gives you the answers and the mini Spy Earpiece in your ear,
  • Mini Spy Wireless Earpiece: captures the special waves emitted by the GSM box to the Earpiece and plays them in the ear.

GSM Box is very eazy to use

A normal SIM card with a number is inserted in the GSM Box. When calling from any phone (be it landline) the number of the SIM card inside, the GSM Box will respond automatically and start transmitting to the Mini Spy Earpiece from the ear what the caller speaks to you.

At the same time, the GSM Box also has a very sensitive microphone that captures the weakest sounds, so the home help listens to what’s going on in the exam room (you can whisper him/her the subjects).

If the exam is very demanding and you cannot whisper the topics then you need a mini cheating video camera that sends LIVE video streaming with the topics. You can find mini cheating camera here

How does the one who dictates know when to call you? It’s a very good question, and the answer is simple: by knowing the time when the exam starts, you set up with the person who dictates you to call you at that time.

You can start and hide the box from home. You will make a trial call to make sure everything works well. After you close this trial call, the GSM Box will remain on Standby- do not worry, the battery will consume very little in the standby state.
