Silent SMS in IoT device tracking and Law Enforcement operations

Silent SMS technology has become a powerful tool for tracking IoT devices and supporting law enforcement surveillance operations. In this article, we will examine the key components of silent SMS technology, its benefits and gain a comprehensive understanding of how to use silent SMS technology.

Silent SMS Technology

Silent SMS, also known as Stealth SMS or ping SMS, refers to specially encoded text messages that are designed to bypass the recipient's device display while triggering status and delivery reports. Unlike regular SMS messages, silent SMS does not generate any visible notification or alert on the recipient's mobile phone. This unique characteristic makes it an invaluable tool for various applications, including tracking IoT devices and enabling surveillance by law enforcement agencies.

The top 5 requirements for silent SMS

For efficient delivery and stealth operation, certain characteristics must be taken into account when sending silent SMS. These attributes should be compatible with Android and Apple iPhone mobile devices and other wireless communication devices used in IOT systems:

  • The SMS is not displayed on the screen of the mobile device in any format
  • There is no notification sound or vibration on the mobile device
  • The SMS is not stored either on the mobile device or on the SIM card
  • The SMS delivery report is sent back to the SMS gateway

    • How do silent messages work

    When sending a silent message, the recipient's device acknowledges the message, but does not display a notification or store the received message.

    Advantages of Silent SMS for Law Enforcement operations

    • Determining the status of a lost person's device. If the person had their mobile device with them, it can be assumed that the person is also there.
    • Collecting information to help investigate a crime without arousing suspicion, and serves as a safe tool for law enforcement personnel during operations.

    Advantages of Silent SMS for IoT Device tracking and monitoring

    Silent SMS technology plays a prominent role in tracking and monitoring IoT devices in various industries. By leveraging silent SMS, businesses can effectively manage and maintain their IoT networks, ensuring optimal performance and operational efficiency.

    • Interacting with IoT devices without disturbing the software running on the device
    • Performance monitoring and troubleshooting support in smart factory
    • Query the connectivity of the mobile devices
    • Facilitating proactive maintenance of smart machines and smart asset management with continuously collected information
    • Increases IOT security and helps prevent unauthorized access
    • Trigger alerts in case an IoT device become sunavailable

    How do you setup Silent SMS system

    Silent SMS sending is a discreet way of the communication that sends specially coded messages. The most important criterion is that the messages arriving on the mobile device remain invisible to the recipients.

    To set up silent SMS, you need to follow a few steps:

    1. Install the Ozeki SMS Gateway
    2. Open the GUI
    3. Select the type of silent SMS message
    4. Enter the recipient's mobile phone number
    5. Set the desired sending frequency
    6. Enter the start/end date/time of the sending period
    7. Configure the attributes to avoid detection by the recipient on your device
    8. Connect to the mobile network
    9. Click the "Send" button to start the silent SMS transmission
    10. Monitor the SMS sending status and delivery report
    11. Check the successful delivery

    Silent SMS delivery methods

    Delivery of silent SMS is possible through different SMS provider connections depending on individual needs and infrastructure. It can be said that, compared to standard SMS, it does not require special infrastructure or SMS subscription from mobile service providers. The type of SMS determines the type of message the message will receive on the recipient's phone. Some common SMS delivery methods are:

    1. Wireless connections: Silent SMS can be sent via standard mobile terminals with mobile origin (MO) SMS messages. This method uses standard SIM card mobile phones and works like traditional SMS.
    2. GSM modems and modem pools: GSM modems, which are standard screenless mobile phones or GSM modem pools connected to a Windows PC, can be used to send silent SMS. Each modem requires a SIM card, and multiple SIM cards can be used in a modem pool for scalability. GSM modems are also used as a communication device for tracking and monitoring IOT devices.
    3. Ozeki's Hardware SMS Gateway: Ozeki's Hardware SMS Gateway, an industrial PC with a built-in SMS modem, enables fast and efficient delivery of silent SMS over 4G LTE and 5G connections. This method is ideal for high speed and reliable delivery. Ozeki's Hardware SMS Gateway is also used as a communication device for tracking and monitoring IOT devices. A big advantage of the Ozeki Hardware SMS gateway is that certain device types can send SMS at the same time and communication via the Internet can also be realized.
    4. IP SMS connections: High capacity SMS sending and receiving, IP SMS connections using SMPP, CIMD2 or UCP protocols can be used to deliver silent SMS messages. These protocols are supported by Ozeki SMS Gateway and facilitate efficient encoding and delivery. The Ozeki SMS Gateway can operate multiple service provider connections at the same time.
