How to make Clone SIM Card

The Ultimate Tool to spy on somebody is in every everybody's pocket ! The Modern Engineering marvel aka Mobile Phone's are everybody's need. People often (mostly) do their confidential talks over cell phone's, But only some know how easy it is to eavesdrop them. There are some tricks and hacks to do that, but the most powerful way is to clone their SIM Card. The Subscriber Identity Card aka SIM Card is the transmitter of signal to the mobile and tower, And you can do It easily.

So What Can You Do When You Clone SIM card ?

 Well There are many things to do when you clone a SIM Card, You can secretly spy on the victims calls and data transfers, make him mobile bill go crazy, send messages and make calls from his number, All without touching the victims Cell Phone.

The following guide enables us to make clones of sim used in india that means you can use one number with two sim card at a 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

Step 6 :

Let The Writing Begin, Select the Write To Disk button and Name the File: SuperSIM.HEX.
