The Subscriber Identity Module aka SIM Card is the transmitter of the signal to the mobile and tower. Our SIM cards contain two secret codes or keys called IMSI (International Mobile Subscriber Identity) and Ki (Authentication Key ), 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 database, it is based on these secret keys that enable the billing to be made to that customer.

Is it possible to clone a sim card?

By extracting these two secret codes from the SIM and program it into a new blank smart card. Since the operator authentication on SIM is based on these values, it enables us to fool the operators into thinking that it’s the original SIM, this authentication is a flaw with the GSM technology.

Now which SIM cards can be cloned?

Not every SIM Card is cloneable, only some SIM card are clonable, let us learn, which one.

SIM cards are manufactured based on three algorithms COMP128v1, COMP128v2 and COMP128v3. It is important to 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, at the time of writing this post.

Access to the victim’s SIM for about 15 to 20 minutes 😉

Step 4: 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.)

Unlock SIM Card

Go to phone tools, select SIM card, then select unlock SIM, it will prompt for a code.

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.

Once they give you the SIM unlock code, enter it, and it will say SIM unlocked.

Step 5: Insert blank SIM card and open USB SIM Card Reader Software not magic SIM at this point.

Step 6: Click connect. It should say ‘No Info Found’ if it is truly blank.

Step 7: Select write to SIM, it will prompt you to select a .dat file, select the one you saved earlier.

Step 8: 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.

        Regards

    • Can it clone a copy of a Verizon CDMA sim to be used in two phones, I have a Samsung and a Blackberry Q10

  10. I in Viet Nam used Viettel mobile. I need to recovery sms deleted already for a long time. So I ask about what brand of the SIM cards data recovery which is suitable in Viettel?

  11. I would like to clone a SIM-card for mobile internet and not for GSM/Phone calls/3g/4g. Some internet providers provide twin and triple cards. This ISP doesnt. I would like to make my own twin card; and have one card in a 4g router in my home and one card in my dual SIM phone.

    The ISP would probably not give away this SIM unlock code the writer of this article refers to. Why would they? It is some times phones that are locked to certain operators but I have never heard of codes for sim cards. Anyone follow?

  12. Will this work on a SIM from a US 4G LTE T-Mobile phone (S7 Edge) put into service 2017?

    I have read a few articles that imply COMP128v1 is no longer used on any new SIM cards.

    I have 2 mobile lines already, I want to be able use different phones and smart watches without having to constantly move the SIM cards. I also like the idea of having a back up in case I lose my phone.

  15. Comment Text*
    sir, i have 2 doubts.
    1. can a blank sim provided by y network providers (eg: given for sim change purpose. 2g to 4g) be used for sim cloning purpose.
    2. from where can i download the software to write into blank sim cards. (u have mentioned not to use magicsim software)

  16. hi,,

    i thought all new sim which have 3g and 4g dont use this algorithm and can’t be cloned this way, using magic sim, does you try with new modern sim..

    i thought this from 2006-2010 sim only

  21. I don’t understand the part about unlocking sim… who do I have to unlock it? Or it’s not the same for different parts of the world…?

  22. Bro I want to clone a sim in my country Nigeria
    But I’m not with the sim. I only have the Number Is that Gonna be possible?

  24. Could someone clone my phone if they had the information about my phone such as the IMEI. I know that my Verizon account information was hacked and that account had the phone specifics. After the date that the man was sitting behind me in Chick-fil-A, with two cell phones in his hand, while I was unsuccessfully trying to pay my bill (using my cellular data), I started experiencing network connectivity problems that had never been present before. Thank you for helping.

  25. I don’t know the following method will work or not bcoz their sim are now secured I have a video which provides step by step method of clone a sim but old method may not work,

    • by the way this post is all about sim cloning not about creating two whatsapp a/c with one no. but you dont have to pull earth on your shouldres, just create whatsapp a/c as you create normally but theres a problem your first account will be automatically deleted after verifying other but there are some other tricks to spy on someone else whats without actually installing it.

  29. Hi i’v got KI and IMSI from old card. I wanna to write this to new “lte”card but i dont have a software. The card is answer to ATR and read her IMSI and KI (like FF FF FF……) but i cant write my original data ?

  30. You said there some tricks that can be used to spy on someone social accounts like WhatsApp.please, can I get to know those tricks without cloning.

  33. Hi I can’t download the usb sim card reader software (last item on the list). Can you provide an alternate or direct download link please? And thank you for the article.

  34. Can CDMA SIM Cards, such as Sprint, and its MVNO be cloned?
    Also you said to get the SIM code from the provider, what about if the phone is already “unlocked” via software such as Galaxy Tools v3.1.8 that unlocks the phone to be used with other providers. If that’s not it, what about if I never set a code for my SIM and my phone says I dont have a code, or are you referring to the 6 digit PUK code, the backup code (in case if the user forgets their pin) or the 4 digit code.

  38. Have a stupid question for you,
    When you say Call network provider for the code to unlock the SIM card, does each SIM card have there own unlock code? Is that code different than the one used for voice mail? We had issues with BTC and we couldn’t unlock and do a lot with the cell phone we just purchased and she gave us the number 1234 and we were able to move forward with programming the phone. In the Bahamas they are very suspicious with every phone call. So I don’t want to setup any red flags.
    Thanks

  41. Hi friend, your post is really very interesting and Now I asked one question how can I get whatsapp message when he is saying:-“Waiting for this message. This may take a while. Learn more”. I and my other friend some time online but this message is not recover. very long time I’m waiting nothing is happen. what am I do?

  42. Thanks for this. I work in an industry that I want to have a nice phone and a junk phone. This write up will help me accomplish that. I bought a new phone to carry to nicer establishments and don’t want to swap the cards all the time.

  43. Will this work on optus sims in Australia and do you really need a PC to use the software or can u download that on an android phone and I’m guessing I’ll need all sims details as in the name and everything it was activated under to unlock it right

  44. SIM successfully cloned, now I have two cards with same number, both in different places, I don’t need to add any cost to that card, but will I listen to a conversation on the other phone with the same number that I have in a different phone?

  48. nice post and also working on it but I need some backup what your name on fb my name is omotoyosi Richie if you don’t mind to add me up thanks

    • yes, one can clone SIM card without access at the time of cloning but one needs the SIM IMSI no. and Authentication (Ki Key), which he/she only can get from the SIM card, i hope you understand, and else all I have said in the post. Thanks for visiting.

  54. Dear Sir,

    Can I send my Sim Card to you to make me a duplicate copy of it. If so, please let me know your fees and if you are require any photos of the Sim Card before sending the same to you. Thank you!

  55. Hello Sir, you said when i call the network provider they will ask me for account info & security code of the sim i want to unlock. How do i reply assuming i’m not the actual owner of the sim I want to clone?

    • No, Chimbonda, PUK code is a different thing, let me tell you;

      Your phone can become blocked in a number of ways – one of them is if you enter your SIM card PIN number incorrectly three times in a row. To unblock your SIM card, you will need to use something called a PUK (Personal Unblocking Key) and that unblocking is different to unlocking.

      I hope you got it 🙂

  59. If you are seeking for solutions to know if your spouse is cheating on you this is something you should try and i bet you this is the best way to clone sim cards to hacks into phones without having physical access to it after that… this has worked for me i hacked into my spouse whats-app messages ,text messages,call logs ,deleted text messages ,Facebook ,viber, kik , emails and many more

  72. if someone calls at original sim card same calls time clone sim card also ring…..if calls pick by original sim card
    so is this possible to same call receive at cloned sim at same time automatically without touch the mobile and listen all conversation without any problem

    • @deepak

      First of all your question is unclear! but as far as I understood, you want the call to be automatically picked up without touching the phone and you want to listen to the conversation, right?

      Listen, only one of the two SIM cards(which have been cloned) can only accept the phone call and other will disconnect automatically, but anyway If you want the phone call to be accepted first from your side, then you can use any Android app to receive phone call automatically without your interaction but this will disconnect the other one!

      Now, common sense, What you would like to receive someone’s call at the same time you’re spying on him/her, think about it?

  77. my husband died 3 years back then after then i moved on with my life and married another man i never knew this man i got married to has a wife in another country and 2 kids this helped me hack into my 2nd husband phone and after the hack was done i was granted full access to my husband phone without physical access to his phone then i got to see all his text, deleted text messages, whats-app, viber and so many after seeing all this i busted in tears. GOD will bless you…

  84. Hi Ansari,

    Have you encounter error “can’t connect to card on this speed. Please change speed then retry again”. My understanding is the serial port usually has 3 speeds to read;9600, 16457 & 19200. The “auto” speed was set by default on the app. Did manual change the speed after “auto” failed, problem still persisted. I have no clue what’s going on, can shed some lights? TQ

  88. I’m really loving the theme/design of your website. Do you ever run into any internet browser compatibility issues?
    A handful of my blog visitors have complained about my website not working correctly in Explorer but looks great in Chrome.

  89. Thanks for this post, please I need someone that can clone a SIM for me, I have been trying this for long time, my Whatsapp number is +44 7497 331437 thanks

  91. It’s actually a great and helpful piece of information. I am satisfied that
    you simply shared this useful info with us. Please keep us informed like this.

    Thank you for sharing.

  94. You should really first say that you will have to call the mobile provider on behalf of the “victim” to have THEIR SIM unlocked. That,s a pretty big step, pretending to be someone else and accessing their account.

  96. I believe everything wrote was very logical.
    However, what about this? suppose you wrote a catchier post title?

    I ain’t suggesting your content is not solid, however what if you added a post title that grabbed a person’s attention? I mean How
    To Clone SIM Card Under 15 Minutes [Full Tutorial] — Tech2Hack is a
    little vanilla. You should peek at Yahoo’s home
    page and watch how they create post titles to grab viewers interested.

    You might add a video or a pic or two to get readers excited about everything’ve written.
    Just my opinion, it might make your posts a little livelier.

  98. Can you clone a sim card without having physical access to it? I mean must you see or touch the sim card you wanna clone?

  99. all this is obsolete, if you want to spy on a cell phone the only thing you can do is pay, buy a spyphone license and you will be able to listen, see and know its position in real time by your GPS.

  100. I love your post. In these days no one is sharing this kind of awsome post. Thanks. I don’t know why, but i love reading all your posts bro. I am a long time follower. Moreover you explained on how to clone the sim Card very well. Nice work as always.

  102. Interesting post. My sim provider does not accept sms from one ‘service’. The ‘service’ sent confirmation sms but I do not get sms from the ‘service’. Is it possible to get sms after clone it. Or is there any other way to get that confirmation sms?
