How to Make Duplicate SIM Card (clone SIM Card)

NOTE: Following information is for educational purposes only!
The following guide enables us to make clones of SIM used in India that
means you can use one number with two SIM cards at the same time.
Before i start off with this guide ,i would like to make one thing clear SIM CLONING is illegal. So please use this guide for personal purpose only,do not use this guide for cheating.
First off a little introduction about SIM CARD:
Our sim cards contain two secret codes or keys called (imsi value and ki
value) which enables the operator to know the mobile number and
authenticate the customer ,these codes are related to our mobile numbers
which the operators store in their vast data base,it is based on these
secret keys that enables the billing to be made to that customer. now
what we do in sim cloning is extract these two secret codes from the sim
and programme it into a new blank smart card often known as wafer,
since the operator
authentication on sims is based on these values,it enables us to fool the operators in thinking that its the
original sim,this authentication is a big flaw concerning GSM technology
Now which sim cards can be cloned:
Sim cards are manufactured on the basis of 3 algorithms COMP128v1,COMP128v2 and COMP128v3
now an important note currently only COMP128v1 version sim cards can be
cloned ,since this is the only algorithm which has been cracked by
users, bear in mind that 70% of all the sim cards we use are COMP128v1 .
OK thats it about the background….. now lets get to the Main Part
1. Buy a Sim card Reader
2.Need a Blank sim card or super sim card
5. Install programs.
6. go in phone tools, select sim card, then select unlock sim, it will promt for a code.
7 call network provider, 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.
8. Once they give you the sim unlock code, enter it, and it will say sim unlocked.
9. remove the sim from your phone, place it in the cardreader, click read from card in magic sim program.
10. 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.
11. Once your ki is found and the crack is finished, click file, save as and save your cracked sim info to a that file.
12. 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.
13. insert black 3g card Use other program, not magic sim at this point.
14. click connect
15. it will say no info found if it is truly blank.
16. 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 network provider gave you, then click finish.
17. 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.
