Factory AT&T iPhone Unlock

As you see we move to the next action after installed driver using instruction #2 for re-write Sim card. This action is most important to perform before re-writing Sim card. Here I show you how to decrypt Sim card. And now you need to use Sim card reader/writer as SCRW.Also I give you some various Sim Ki decryption software that you can use. You can choose any of them:

  • Ki Decryptor v1.0 – is for Sim cards till 2010
  • Ki Decryptor v2.0 – is for Sim cards from 2010 and later
  • SIM Master download here
  • Multi Sim / Sim Scan download here

If your antivirus says that these program software are affected by virus, just ignore it.

Some info that you need to know

  • Program software above was tested with China Mobile and China Unicom SIM cards.
  • There is a problem with latest Sim cards. Sometimes it is impossible to decrypt them
  • Auto-blocking option exists in some Sim cards. That means if you use decryptor your card block itself and you and I can do nothing with that.
  • If you want to insert or remove Sim card from the card reader, first you have to unplug the SCRW
  • The SIM card RW supports 2 speed – 9600 and 19200 baud rates

Decrypt Sim Card And Re-Write It

Use these steps to decrypt Sim card

Step 1. Select the SCRW’s baud rate to 19200 with a small pin. This gives quicker decryption process. There is a method to use 9600 if it doesn’t read the SIM card correctly.

Step 2. Insert SIM card into the SCRW.

Step 3. Launch SIM card decryptor v1.0 or v2.0). This software will let you determine the year your SIM card was made.

Note: when Ki Decryptor doesn’t start – set the Language for non-unicode programs to Chinese (PRC).

Windows 7 or Vista: Control Panel => Region and Language => Administrative tab => Click Change system locale to Chinese (Simplified, PRC).

Windows XP: Control Panel => Regional and Language Options => Advanced tab => select Chinese (PRC).

And now perform this:

  • Choose the COM port you add during driver installation. Select baud rate 19200.
  • Choose the first tab for decrypt status
  • Click on this button to attach to SCRW
