Sim cards are manufactured on the basis of 3 algorithms: COMP128v1, COMP128v2 and COMP128v3

It enables us to fool the operators in thinking that its the original sim this authentication is a big flaw concerning GSM technology. 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.

Our sim cards contain two secret codes or keys called (imsi value and ki value) which enables the operator in identifying the sim card 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. Sims and making calls worth thousands through it recently many gsm operators in india have set up surveillance techniques to trap people who use cloned sims. So i once again request to everyone that please use this guide for personal purpose only,do not use this guide for cheating.įirst off a little introduction about SIM CARDS

I have compiled them all together and made one simple guide which can be followed even by vering only the relevant things needed to know rather than going technically deep. Before i start off with this guide I would like to make one thing clear, SIM CLONING is illegal! There have been many cases in india where people have been caught for cloning others The following guide enables us to make clones of sims used in india unlike the complicated guides you find on the net.
