I believe 80% of People don't know about SIM Cloning. What is SIM Cloning? Could a SIM be cloned!! Yes, It Can.
Why am writing about it here, there is a reason. I work under an industry, where I don't have the freedom to share about issues. And people makes fun there of technology impacts. There are lots of Telecommunication industry in today's world who provide network communication support. But those people who provides the support, most of them are unaware of technology growth and technology impacts. One of the biggest section in "Customer Support", specially Billing Section. A customer Faces a bill of 600 pound, normally at home. The customer said, it couldn't be so much bill. But the adviser argues, as the bill is made by him/her. The adviser even said him, "The bill is been made from your SIM, and SIM could not be cloned" .
This feedback, I cannot accept. That's the impact and poor innocent customer have to pay the large amount of bill.
SIM Card cloning is possible. How does this happen? Basically, a sim card is a chip in normal work and it contains specific two elements,
a) IMSI Value (Like IMEI Number of Cell phone. It contains total 15 digit, written in back of SIM. This 15 digit is divided into three section. The Mobile Country Code (MCC), the Mobile Network Code (MNC) and the Mobile Subscriber Identification Number (MSIN). The MCC is 3 digits, the MNC is 2 or 3 digits, leaving 9 or 10 digits for the MSIN.)
b) Ki value (Written inside SIM)
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, 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.
SIM cards are manufactured based on three algorithms COMP128v1, COMP128v2 and COMP128v3. It is important note currently only COMP128v1 version SIM cards can be cloned, since this is the only algorithm, which has been cracked, bear in mind that 70% of all the SIM cards we use are COMP128v1.
1. Buy a SIM card Reader
2. Need a Blank SIM card or super SIM card .
3. Download and install MagicSIM
4. Download and install USB SIM Card Reader Software 3.0.1.5
5. Go in phone tools, select SIM card, then select unlock SIM, it will prompt for a code.
6. 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 SIM card, just tell them you need to unlock your SIM to get it to work with your overseas phone or something.
7. Once they give you the SIM unlock code, enter it, and it will say SIM unlocked.
8. Remove the SIM from your phone, place it in the card reader, click read from card in magic SIM the application.
9. When it displays ‘connected’, select crack SIM in the toolbar. Click strong ki and select all of the other find options and then click start.
10. Once your "KI" is found and the crack is finished, click file, save as and save your cracked SIM info to a file.
11. IMPORTANT!!! You must click disconnect from the file menu or you will ruin your SIM card.
Once it says disconnected, remove the SIM. Put the SIM in your phone and see if it still works, it should. (If not, either you did not unlock your SIM, or you tried to copy it instead of crack and save.)
12. Insert blank 3g card USB SIM Card Reader Software3.0.1.5, not magic SIM at this point.
13. Click connect
14. It should say ‘No Info Found’ if it is truly blank.
15. Select write to SIM, it will prompt you to select a dat file, select the one you saved earlier. 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 the network provider gave you, then click finish.
16. Your card is now cloned.
It should be noted that if you try to make two calls at the same time, one will connect; the other will say call failed, both phones will get the same messages, text and voice, and both will receive the same calls, but only one can talk at a time
In This way SIM Cards are Cloned or Hacked, due to which Victim Customer gets a lot monthly bills, without using the services. My issue behind sharing this, so that each innocent people should know the impacts and do not get forced to pay the bill. They can fight for there issue.
