How does it work?

XCell Dynamic IMEI v2 is capable to detect any changes made by a GSM interceptor on a GSM network, in order to register or attract the phone on the fake network (GSM Interceptor Proximity Alert). Phone registration on a new BTS (the fake BTS generated by a GSM interceptor) is an automated process and this behavior is absolutely common on any cell phone. Any cell phone will automatically choose the most powerful GSM signal, which in case of interception is generated by the GSM interceptor. GSM interceptors (active and semi active ones) force the cell phone handover by suppressing the real network signal with a powerful signal and by mimicking network parameters: MCC, MNC and LAC. But the ARFCN (communication pair channels) and Cell ID are changed in order to force the phone to send registration requests on the “new” BTS. XCell Dynamic IMEI detect these changes and will warn you: a discrete open lock icon will be displayed on the home screen. Same open discrete lock icon will be displayed on active call, in case of call interception (Call Interception Alert).
Along with the home screen warning display, the phone warns you by sound/vibration alert.

If the network characteristics change i.e. using a GSM interceptor or IMSI catcher, or any method to try and trick the SIM into changing to a breakable A5/2 encryption, the phone will detect this and alert the user via an alarm, vibration or display a screen message. No calls or SMS’s can then be made.
The handset will also randomly change the IMEI on each call, or you may specify an IMEI. A good way to confirm the handset does change the IMEI and not just gives the appearance of a different IMEI is to assign a known blocked or stolen IMEI to the handset.

Also, the phone will alert you when receiving an abnormal number of GSM network re-registration requests (UnPing feature), coming from network itself or from a GSM interceptor which is trying to locate the cell phone or is running a Kc extraction (communications ciphering key) from your SIM card. The phone can be locked to a specific GSM channel number (ARFCN), in order to avoid BCCH manipulations procedures performed by GSM interceptors. XCell Dynamic IMEI v2 will show on home screen the TMSI value, which will remain the same in case of phone interception. The phone will delete automatically the call log after each outgoing or incoming call and all incoming and outgoing call audio will be automatically recorded without emitting any background beeps. All recorded files can be re-played directly from the phone.

The phone can be used in two modes: Hunting mode and Anti Interception mode.

1. Hunting mode:
XCell Dynamic IMEI v2 is the only phone that can actually hunt GSM interceptors, by detecting them in real time. On Hunting mode the phone user will get alerts whenever the phone is intercepted by active, semi active and passive interceptors, or even with the help of GSM operator. Hence, the phone user can fill out any story based on art of deception, can lead counterintelligence special operations, can simply remain silent or even switch off the phone.
For Hunting mode operation please go to Extra menu, enter password, A5 tracer, A5 change alert, uncheck HandOff option by checking any other alerting option. Otherwise, phone conversation automatically breaks in case of phone interception and HandOff option is checked.

2. Anti Interception mode:
Once the phone get intercepted by any means (GSM interceptors or carrier), any incoming or outgoing call and SMS will be automatically blocked until the threat is over. For Anti Interception mode operation please go to Extra menu, enter password, A5 tracer, A5 change alert, check HandOff option. From now on, phone conversation automatically breaks in case of phone interception.
