how to clone (duplicate) a sim card

[Guest dwnhiler]

i have a small dillema i want to use a nice phone but my cars bluetooth wont recognize the phone usually what the car recognizes are usually the not so nice phone so i want to be able to have 2 sim card that way i will only have one phone number but shared throuh 2 phones . with land line phones this is possible, but i wonder if this would also be possible with the sim card that way i could have 2 phones and it would be upto me to choose which phone to answer just like a land line phone i would greatly appreciate it if someone who is very clever at this could help me out thnks

GSM-Technology seems to have a "BACKUP" utility available...

Is this not illegal though, even if it's your own sim card...? Like coping dvd's and such are you allowed a backup...?

SIM cloning consists of (often illegally) duplicating the GSM Subscriber Identity Module (a SIM card must be entered into a GSM phone in order for it to connect to a network, except for the basic GSM emergency 112 calls or local emergency calls (like emergency 911 calls for the United States) identification and placing calls or using other charged services using the account of the cloned SIM.

In the early 1990s, due to poor security, cloning was more common than it is today. Cloning has now been rendered more challenging technically (as physical access to the SIM card is required as opposed to simply being within radio reach).

SIM cloning is now more difficult to perform, as merely duplicating the contents of the SIM does not enable a duplicate SIM to operate, as the SIM itself performs security operations on the data contained inside to avoid such copying. In order to function, the cloned SIM needs to perform security operations on the data contained, just like the 'original' one.

SIM cloning is a great concern of security/police services as it renders GSM location-based service (LBS) unreliable if more than one handset is using the same SIM.

In the movie The Bourne Supremacy, the main character clones a SIM card to enable him to impersonate a foreign agent. It is widely held that actually cloning a SIM could not be accomplished as quickly as it was in the film.

Real time for extracting KI from a SIM card is approximately 4-8 hours. There is 40% probability of damaging the card in the process. Additional problems are that the attacker must know the SIM Card's PIN(CHV1).

Cracking Ki by overhearing radio GSM traffic is difficult but not impossible. In many countries GSM traffic is not encrypted thus with proper equipment (although this equipment is very expensive and not available for everybody) a hacker could overhear GSM traffic and clone SIMs.

The security has been improved with the newer generation of SIM cards to be used with 3GSM networks, known as USIMs. The new specification implements a new publicly announced algorithm (the KASUMI algorithm).

jessy what did you do to learn and to acquire so much knowledge on this, you guys amaze me. but im an eagger learner i know im a newbie but willing to go the footstep you went through.

does the cingular and tmobile use a sim that might take running scan more than 65536 times.

Sorry folks. Discussion is sim cloning is a little too illegal to be within forum rules.
