With that short insight, you should have probably figured out that the main goal in cloning SIM card is to get the KI and IMSI keys. These keys are the identifier of the SIM card and help to register the SIM card on the mobile network.
Cloning the SIM card definitely comes with great power. Much as you must always remember that its illegal. You can do quite a lot. Imagine spying on the victim, sending messages and making calls from a victim’s number and etc.
A major flaw with the GSM technology allows us to program the two keys extracted from the operator into a new blank smart card. The operator authentication on SIM is based on these keys and therefore it gives us chance to fool the operators into thinking that it’s the original SIM card.
