IMEI AND THE ILLEGAL USE OF FLASHERS
International Mobile Equipment Identity (IMEI) is a unique 15 digit international serial number used to identify a mobile phone handset to a mobile phone network. This number can used to identify illegal mobile phone handsets.
Each time a mobile phone is switched on or a call is made on it, the network provider checks the IMEI number of the handset, then it cross references it with a blacklist register such as the Central Equipment Identity Register (CIER) used in the United Kingdom. If it is on the blacklist then the network will either refuse to send a signal to the phone or will supply a signal but will not allow any outgoing or incoming calls (UnlockMe 2007).
Flashers can be illegally used to change the IMEI number of some mobile phone devices. This in effect enables criminals to illegally re-enable stolen or lost mobile phones that won’t be otherwise usable on a certain mobile phone network.
Figure 1 below is a screen shot of the flasher software for UFS3 by SarasSoft that shows the option to change (rebuild) the IMEI number of the mobile device under the Aux features box within the DCTL group of devices options for the Nokia mobile phone brand flashing. It is worth noting that for Nokia, only DCT3 and DCTL group of devices allow for IMEI modification. Newer Nokia mobile phone devices embed the IMEI number in a non-re-writable chip and therefore are not subject to IMEI rebuilding.
