What is SIM Interposer?

SIM Interposer works by adding an EEPROM chip to your SIM card just like a TurboSIM. You then call 112, a number that can be called from any GSM phone, free of charge, with or without a SIM card on any compliant network. Once the call connects you hang up then toggle Airport mode on and off. When the network connection resumes you will be unlocked.

How it works?

Step 1: Turn of your iPhone 4 and insert your SIM card and GEVEY SIM together with the metal SIM tray provided.

Step 2: Turn on your iPhone and wait for the SIM Welcome menu to show and then select accept.

Step 3: At the beginning a no service message will show on your iPhone. Do not do anything and wait until you see one signal bar appears on the top left corner.

Step 4: After you see the signal bar you dial 112and hang-up within 2 seconds.

Step 5: Turn on the Airplane Mode and then turn off right away. Your iPhone will show SIM Failure and then No SIM Card Installed.

Step 6: Until the No SIM Card Installed message shows up turn on the Airplane Mode again and turn it off right away again. The SIM Failure message will show and the signal will show up after a few seconds.

Your iPhone 4 should now be unlocked on baseband 02.10.04, 03.10.01
