Time is of the essence. That's why you can trust our express delivery service to get your Stealth Phone to you quickly and safely.

Stop hiding

Concerned about being tracked or observed? Imagine your phone is in your pocket, but shows anyone trying to track you that you are 1-10km away in another location. With location spoofing, your phone’s location is no longer tied to your physical presence. Move around with confidence, knowing that your true location remains protected and private. Experience the freedom and control location spoofing gives you.

Be invisible

Thanks to robust defensive security features, you benefit from unlimited user identities, ensuring you are no longer vulnerable to interception and can enjoy complete anonymity.

Start fighting back

Powerful offensive security features give you the ability to defend against abusive interception, meaning you can launch attacks to protect your goals and interests while maintaining secure communications.

Perform at best

Secure communications keep your secrets safe and increase your efficiency in fullfilling your responsibilities. This will ensure that you save valuable time, allowing you to focus more on your personal and professional success.

Personal Intelligence Agency

Our interception detection features give you access to your own personal intelligence agency. This means you will be notified of any threat, interception or tracking attempt, giving you the opportunity to make the right decision at the right time. Being alerted at the right time can make the difference between success and failure, growth and decline, and in extreme cases, even life and death.

Impenetrable Vault

In a world where your personal data and valuables are constantly at risk, you need a secure and reliable solution. Imagine a world where you never have to worry about your sensitive information falling into the wrong hands. Furthermore, imagine a worst-case scenario where you can rest assured that your most valuable data is locked away in the most secure vault available – your Stealth Phone.

Special Functions

Defensive & Offensive Security

Get ahead of threats with powerful defensive and offensive security features

IMEI Change

Change your phone. With the IMEI Change feature, you can alter your phone's identity, making it difficult for GSM Interceptors to track or intercept your communications. Combining IMEI and IMSI changes ensures your calls, SMS and location remain completely secure and untraceable, giving you a new phone and SIM simultaneously.

IMSI Change

Change Your SIM. The IMSI Change feature generates new, valid IMSI numbers on the fly, effectively providing a new SIM card with each change. This ensures your communications remain untraceable. Seamlessly clone any SIM card and use a virtual SIM instead. Stay protected without relying on the Internet, special SIMs or additional costs.

Mode

Adapts to your needs. Mode allows you to easily switch between Hunting Mode, which detects and alerts intercepted calls and SMS, and Anti-Interception Mode, which blocks all communications during active monitoring. This flexibility gives you complete control over your communications security, ensuring you are protected in every situation.

Channel Lock

Lock in your security. The Channel Lock feature locks the uplink and downlink radio channels used for communication between your phone and the cell tower. This prevents forced handovers and stops your phone from connecting to fake towers used by GSM Interceptors. Avoid Interception by staying on real towers.

XTerminator

Neutralizes threats. XTerminator launches a potent OTA attack against IMSI catchers and GSM Interceptors. It floods uplink channels with fast connection requests via RACCH, similar to a DoS attack. This stealthy approach is undetectable to interceptors, ensuring maximum disruption.

Sentinel

Keeps your phone anchored. Sentinel's anti-standby mode simulates an ongoing call, preventing your phone from connecting to other cell towers. It locks onto the current tower by continuously sending immediate assignment requests. The result is a stable connection and protection against IMSI Catcher interference.

Secure Comms & Location Management

Your words and movements protected and empowered

Secure Call

Protected when it counts. Encrypt your calls with MLSP® technology, using quantum-resistant cryptography that connects directly over the cellular network between PRO and ULTRA devices - no servers, no internet, no subscriptions. Bulletproof encryption when you need it, seamless calls when you don't, to call any phone.

XCrypt MLSP

Privacy in every message. XCrypt MLSP® is a groundbreaking encryption solution that secures your SMS communications like never before. Using patented quantum-resistant cryptography, your messages are encrypted directly via cellular network between PRO and ULTRA devices - no third-party servers, no data connection, no Internet required.

Sat Comm

Connect globally. Communicate with phones anywhere using satellite connections, even when cellular networks are jammed or blocked. SatCom serves as a critical fallback for connectivity in challenging situations. Requires additional hardware and a monthly subscription. Interception alerts keep your SatCom secure.

Cross-Platform Encrypted Messaging

Third party E2E apps. Communicate securely with any phone using encrypted third-party apps to ensure your messages, pictures, and videos remain private. While Threema is available for installation, additional encrypted apps can be added upon request to keep your communications safe from prying eyes.

Location Spoofing

Control your location. Use cell tower selection to keep your true location concealed by connecting to the most distant cell tower. Your phone will appear to be 1-10km away from where you actually are, ensuring that tracking systems and the network operator cannot pinpoint your real position. Enjoy the freedom of secure and private movement.

Monitoring & Alerts

Make better decisions with real-time monitoring and instant threat alerts

Spyware Detection

Advanced spyware defense. Safeguard your phone from abusive and sophisticated government-grade spyware like Pegasus and FinSpy, as well as any malicious code. The phone blocks forced and remote code execution, ensuring your device is protected against any spyware installation.

A5 Tracer

Identify the threat. A5 Tracer alerts you to any voice or data interception. Although calls and messages are encrypted by default, GSM Interceptors can force your phone into unencrypted mode (A5/0). This feature allows you to react quickly and take action to protect your privacy.

C2 Monitoring

Detect rogue networks. This feature monitors network parameters to identify when GSM Interceptors force your phone to connect to fake base stations using BCCH manipulation and other techniques. It alerts you to anomalies by comparing signal strengths and neighboring cell towers.

cryptoTRACER

Detect Lawful Interception. This feature identifies if your calls or SMS are being monitored by operator assistance, abusive state actors, or other agencies. It uses advanced technology to scan for interception attempts and alerts you immediately if any SS7 interception is detected.

Network Scan

Live detection and analysis. This feature offers real-time monitoring of your network to detect IMSI Catchers, GSM Interceptors, and SS7 interceptions. It utilizes intelligent scanning to provide accurate alerts with no false positives. Rest assured, no threat goes undetected.

LAC Change detector

Stationary threat detection. This feature detects abnormal Location Area Code (LAC) changes that should only occur when you are moving. If LAC changes are detected when you're stationary, it signals GSM Interceptor activity, alerting you to interference. Peace of mind in the environment you trust.

Location Tracking Alert

They Track, We Detect. This feature alerts you when your phone receives location tracking pings or when there’s an attempt to extract the encryption key (Ki) from your SIM card. Stay protected and aware of any unauthorized tracking or key extraction activities.

No Signal Alert

Detect signal disruptions. No Signal Alert continuously monitors your SIM card and network for signs of GSM Interceptors trying to force your phone to connect to fake base stations. It provides instant alerts to keep you aware of any network tampering.
