SIM chip cloning instructions

Without further delay, here is exactly how DonJuan successfully cloned his SIM chip:

Buy simcard reader/writer.

Buy blank 3g simcard

Download Magicsim at http://www.magicsim.com/en/multi-sim.asp?new_id=6

Download http://www.filecart.com/Windows/System-Utilities/Backup-Restore/USB-SIM-Card-Reader-Software_1711_1.html

Install programs.

Go in phone tools, select sim card, then select unlock sim, it will promt for a code.
Call AT&T, they will ask for your phone number, your account info, name and security code, then they will ask why you want to unlock your simcard, just tell them you need to unlock your sim to get it to work with your overseas phone or something.

Once they give you the sim unlock code, enter it, and it will say sim unlocked.

Remove the sim from your phone, place it in the cardreader, click read from card in magic sim program.

Once it says connected, select crack sim in the toolbar. click strong ki and clink all of the other find options and then click start.

Once your ki is found and the crack is finished, click file, save as and save your cracked sim info to a dt file.

IMPORTANT!!! you must click disconnect from the file menu or you will ruin your simcard. once it says disconnected, remove the sim. put it in your phone and see if it still works, it should. if not, you either did not unlock your sim, or you tried to copy it instead of crack and save.

Insert black 3g card Use other program, not magic sim at this point.

Click connect

It will say no info found if it is truly blank.

Select write to sim, it will promt you to select a dat file, select the one you saved before, now click start, it will take about 10 minutes to write it, once it is complete, it will ask for a security code, enter the security code AT&T gave you, then click finish.

Your card is cloned. if you try to make 2 calls at the same time, one will go through, the other will say call failed, and both phones will get the same messages, text and voice, and both will recieve the same calls, but only one can talk at a time.

Caveats and warnings about cloning your SIM card

As of yet, I have NOT attempted to follow DonJuan’s instructions so I cannot confirm whether or not this process works. I did download both of the required applications in preparation for my future attempt. Therefore I should point out that I uploaded one of those applications to Virus Total to have it scanned for viruses. I was disappointed to see that F-Secure found one piece of questionable code in the Sim Card reader software listed in step 4. On the other hand F-Secure only represents 1 out of 36 scanners on Virus Total therefore it’s up to you to decide whether or not to install this application.
The MagicSim software unfortunately was too large for Virus Total so I have no idea whether this application is virus free or not. I recommend that if you decide to follow DonJuan’s instructions you do so on an extra computer (one you’re willing to infect with viruses if it comes to that) or install something like VMWare and install these applications in a virtual computer running inside of your current computer. This way, if these applications do have viruses, you can simply kill the infection by deleting the virtual computer.
All that being said, clone your SIM chip with this process at your own risk. As I already mentioned, I have NOT validated these instructions with my own test. I simply put them in a dedicated article on this site because I said I would do something like this if someone provided a detailed list of instructions. If you follow DonJuan’s instructions, and have success, please post a comment here and share your experience with the rest of the TechTraction readers.
Please Note: Keep in mind that blatant SPAM urls added to comments will be removed.

 

The article explained why such action wasn’t possible with a SIM card reader and basic software. Since that article, the reader comments have been consistently flowing in and the article remains one of my most frequently read items. Despite my explanation, some readers have claimed that they have succeeded at what I said was impossible. Unfortunately, when pressed for details, responses where either nonexistent or lacking critical details. Fortunately, all that changed on 9/26/2008 when reader DonJuan posted a detailed response that might just do what many of us want to do with our SIM cards.
