Mobile technology has never played a more critical role in personal security and fundamental rights than it does right now. XCell Technologies is uniquely poised to address the dangers of mobile interception used illegally or abusively by the state toward its citizens, following shortsighted policies.

There’s been a lot of talk about Android Stealth Phones since 2014 when we released our first Android Stealth Phone under the Law Enforcement Product Line. It took us four years to develop the most advanced and secure Stealth Phone of its time: XStealth.

But the best is yet to come, and the journey doesn’t stop there. The next big things are here. There have been no perfect Stealth Phones until now. The upcoming Android Ultra Secure Stealth Phones generation has been successfully rolled out.
After another four years of development and testing, XStealth ULTRA and XStealth PRO have officially launched and are available for ordering.

What do you expect from a Super-Stealth Phone? No comprimises, right? After all, it’s about your security and privacy. Well, with the new XStealth Phones, you’ve got everything—the best of both worlds—privacy and security.

Both devices are extensively tested on all significant interception systems and behind enemy lines in the hottest military conflicts. Right now, they are intensively used by field operatives and confirmed by our main clients as the most suitable for covert actions when being a step ahead of your enemies can be the difference between failure and success.
Based on the new XStealth military version released in 2020 and packed with new and unprecedentedly unique functions, XStealth ULTRA and XStealth PRO are now available for public use.

What’s new?

Before everything, it is all about trust. The trust should not only be presumed but tested. You asked for it; now you have it. We have implemented 27 testing procedures for every special function, including the Call Interception Alert. Now, every phone user can test all special functions at any time. No other secure cell phone manufacturer offers this option to users. More about testing XStealth ULTRA, here: How To: Test your XStealth ULTRA

1. A new function has been added: Voice Call Encryption, based on our MLSPⓇ patented technology. No data or internet connection is needed, and no third-party servers are involved in your secure call. There are no fees, payments, or hidden strings. It’s 100% free, secure, and private.
2. IMEI and IMSI Change functions are now working for both SIM cards.
3. The Calibrate function now allows users to run it anywhere, even near a GSM Interceptor. When abnormal network parameters are detected, Calibrate stops and warns the user.
4. The Change IMEI function has a new addition: Classmark capability. The phone can keep its Classmark when the IMEI is changed or can generate abnormal Classmarks when fighting against interception systems.
5. Added LAC/TAC Change alert for 5G bands (XStealth ULTRA).
6. Added Call Interception detection on 4G and 5G/LTE bands, fighting against the newest native 4G and 5G interception systems that do not need to downgrade the network technology (from 4G to 2G, for instance) for call interception.
7. New Function: Network Downgrade Alert. This function alerts users when an interception system forces the phone to downgrade from 4G/5G to 2G for call/SMS interception purposes.
8. The location Tracking Alert function has been improved. It is now responsive to LTPs (Location Tracking Pings) sent over 4G and 5G networks.
9. The new XPing Tool is compatible with Android 12, 13, and 14. Improved LTP handling.
10. A new function has been added: No Signal Alert. This function alerts the user when a passive interception system attacks the phone.
11. A new function has been added: No Signal Alert 2. This function alerts the user when the phone is attacked by an old type of GSM Interceptor that uses FR jammers to force the phone to use 2G bands.
12. To preserve battery power, the user can change the network scanning speed.
13. Improved battery life: up to 3 days for moderate data/GPS/Bluetooth use and 2 days for intense use.
14. Improved XTerminator over-the-air attack against IMSI Catcher/GSM Interceptor. In addition to 2G and 3G bands, 4G and 5G bands are now used for attack.
15. One-touch Security button: The user can enable instant security and privacy by tapping a single button. This feature is useful in various scenarios, including covert actions.
16. IMSI Catcher/GSM Interception detection improved: instead of 6 cell towers, now the phone can “see” up to 30 neighboring cell towers.
17. Changing IMEI now complies with all national laws. The original IMEI can be restored at any time, and the displayed IMEI will always be the same (when dialing *#06#)  but different from the one used to connect to the mobile network.

Android Super-Stealth Phones now come in two flavors. Both are complex products that are easy for regular people to use.
