    • 2Multi-network roaming prevents single-carrier tracking
    • 3Zero IMSI broadcasting means catchers get no identity data
    • 4Silent SMS and ping attacks are blocked at network level

    How Our Encrypted SIM Prevents IMSI Catcher Tracking

    IMSI catchers (also known as Stingrays or cell site simulators) work by pretending to be the nearest, strongest cell tower. Your phone naturally connects to the strongest signal – which is exactly what these surveillance devices exploit.

    How GhostSims Defeats IMSI Catchers

    Random Tower Selection

    Unlike standard phones that automatically connect to the nearest tower, GhostSims selects tower connections randomly – not based on signal strength. It avoids predictable connection patterns so IMSI catchers can't anticipate your behavior.

    Multi-Network Roaming

    GhostSims uses advanced multi-network roaming, connecting to different carriers throughout the day. This prevents single-carrier tracking and creates no consistent network footprint.

    Zero IMSI Broadcasting

    The most powerful protection: GhostSims never broadcasts your IMSI. Your IMSI is masked at all times, so IMSI catchers receive no useful identity information.

    Blocking Silent SMS and Ping Attacks

    IMSI catchers and surveillance systems often use silent SMS (Type 0 SMS) to ping your phone without notification and confirm your presence in an area. GhostSims blocks these attacks at the network level – no ping responses are sent and your presence remains undetectable.
