What is Gevey SIM?
Gevey SIM - It is actually not a sim. It is a sim interposer.
An interposer is an electrical interface that directs the connection from one socket to another.
The purpose of a sim interposer in this case is tore-route a connection to a different connection which can then unlock the iPhone 4.
HOW TO USE:
You need to dial 112 ONCE when first to use Gevey Express, no need to do it again when reboot the iPhone 4:
Step 1. Turn off your iPhone 4 and insert your Sim card and Gevey Express Sim together with the metal Sim tray provided.
Step 2. Turn on your iPhone 4 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 4, DON'T do anything and wait until you see one signal bar appears on the top left corner.
Step 4. After you see the signal bar dial '112' and hang up within 2 seconds.
Step 5. Turn on the Airplane mode and then turn off right away. Your iPhone 4 will show "SIM Failure" and then "No SIM Card Installed".
Step 6. Until the "No SIM Card Installed" messages shows up turn on the Airplane mode again and turn it off right away again. The "SIM Failure" messages will show and the signal will show up after a few seconds.
Step 7. In Setting, make sure you select your phone provider so next time the Card can remember it.
You only need to set up the iPhone 4 once with the Gevey Express SIM Card. The Gevey Express SIM card will remember the first setup. After that,each time when you turn on the iPhone 4, a message comes up, click "CANCEL". Wait for the iPhone 4 to find the phone provider.
NO REPEAT SETUPs NEEDED!!!
