How does it work?

Using a SIM card reader, the information on your SIM card is decrypted and exported to a file. This file contains your SIM card’s ICCID, IMSI and Authentication Key (Ki) etc. A special software is then used re-write these information and the same embedded program used in the Gevey Turbo SIM onto a new SIM card. The screenshot below shows the output file that contains information from the original SIM card.

This method has been proven to work but requires a bit of time and effort. Generally, the process of exporting the information from your original SIM card will take between 5 minutes up to an hour. Once the information is exported, you will need to use a SIM writer software to write the information on to a new SIM card.

Here’s what you need for this hack:

  1. USB SIM card reader/writer
  2. SIM card decryption software
  3. SIM card writer software
  4. Your own SIM card
  5. Blank SIM card

Once you have hacked the new SIM card, you will need to do the following to unlock your iPhone 4. Note that you will only need to do this ONCE:

  1. Insert your own SIM card.
  2. Dial 112 and drop the call.
  3. Turn on Airplane Mode, insert hacked SIM card and turn off Airplane Mode. Your phone will connect to the network automatically.

The next time you reboot your iPhone – you won’t need to repeat the steps above anymore!

One of the best things about this hack is that you can repeat it on an unlimited number of SIM cards, for as long as you have blank SIM cards available; ideal for those who want to earn extra money or for mobile phone repair shops operators.

  1. where is the software available from?
    Willing to test. but dont have writing and decrypting tools. All i have is blank sims and a sim writer.


  2. I have an iPhone 4 with iOS 5 installed on it and the baseband is 04.11.08.
    Can I make use of this tool to get my iPhone unlocked ?

  3. I have an iPhone 3GS iOS 4.2.1 with baseband 5.15.04, does the sim writer software really work to unlock my iPhone?

  4. Does it only work with my sim card that i used to decryped or it work with others as well? incase if I want to sell the phone and people ask if its unlock.

  5. I am not sure if it will work with V2 SIM (new generation SIM cards) …. as far as I know the data on v2 SIM cards cannot be decrypted (because of 128 bit strong encryption) and thus cannot be re-written!! can you confirm?
