STEALTH-PHONE

Untraceable GSM Mobile Phone

It warns you about any intrusion attempt

Siemens S65, changed into an untraceable device, warns you against any interception attempt. Every time you change SIM card, the phone will change automatically its IMEI number. The IMEI numbers are produced by the phone randomly and will never be repeated. Interception of conversations made or received by such a phone becomes an impossible mission.

Over the past decades, telecommunications interception has developed into a huge worldwide industry. Intelligence agencies, security organizations and police within almost all countries routinely intercept calls that may yield sensitive political, military or economic information.

The use of wiretapping has become so widespread, simple and uncontrolled that you must assume that records of your private calls end up in the wrong hands.

There are variety devices on the market today to encrypt your conversation. Though using of encryption to protect your privacy might be the prudent choice, the method has its own disadvantages:

• You never know if encryption you use is indeed trustworthy and there is no reliable way to check it.
• Using of such devices might make you looking suspicious and attract undesired attention to your personality.

Understanding that and trying to look innocent, people often implement another method available in any country with GSM coverage. They buy a few anonymous SIM cards and replace them from time to time. Now, being under impression they are safe, they talk freely doing sometimes a terrible mistake.

Interception equipment connected to switches of GSM network provider (so called "Lawful Interception") almost never satisfies with tracking targets by identities of their SIM cards (IMSI). It also monitors identity of GSM handsets (IMEI). So, to be untraceable, both the SIM card and the handset should be changed together.

It is Siemens cellular mobile phones we have modified to turn those into untraceable device. Every time you replace SIM card the phone automatically will change its IMEI number. The IMEI numbers are produced by the phone randomly and will never be repeated. Interception of conversations made or received by such a phone becomes an impossible mission.

Understanding of IMEI (International Mobile Equipment Identity)

IMEI stands for International Mobile Equipment Identity. The IMEI is a unique 15-digit code used to identify an individual GSM mobile telephone to a mobile network. The IMEI can be displayed on most phones by dialing the code *#06#. It is also usually printed on the compliance plate under the battery. The numerical format of the IMEI code is: 111111-22-333333-4. This format will be in place until April 1st 2004.

• TAC: type approval code
• FAC : final assembly code
• SNR: serial number
• CD: check digit

The TAC (Type Approval Code) is formed by the first six digits of the IMEI. This code identifies the country in which type approval was sought for the phone, as well as the approval number.

NOTE: From 1st April 2004 the TAC will be the abbreviation for Type Allocation Code.

The FAC (Final Assembly Code)identifies the company that produced the mobile phone (for instance: Sony-Ericsson or Nokia).

The SNR (Serial Number) is a six digit code, which has been uniquely assigned to the specific type of handset. The CD (Check Digit) is used to check the IMEI for its validity for Phase 2 and Phase 2+ handsets. Phase 1 GSM handsets, however, always have zero (0) as check digit.

NOTE: From 1st January 2003 a new IMEI allocation procedure is in place. The changes relate to the format of the IMEI; the Final Assembly Code (FAC) will be obsolete and be set to 00 for the period from 1st January 2003 until 1st April 2004. After that the FAC will be obsolete, and the TAC will be eight digits in stead of six digits. The numerical format of the IMEI code will then be: 11111111-222222-3:
