Insert the GEVEY Ultra S SIM and the GEVEY reset SIM together into the iPhone 4S and the list of carriers will be displayed. (the reset SIM is the white SIM card that came with your GEVEY Turbo SIM)
2: SELECT THE ORIGINAL NETWORK
Once you enter your Gevey along with the Reset card, a network list will pop. Select the phone origianal network or it’s IMSI code if the network is not on list and click accept.
After you clicked accept, a confirmation message will show.
(Note:You might need to wait up for the confirmation screen to appear.)
When the confirmation screen appears, you have successfully unlocked your iPhone 4S! You can select either “Cancel or Accept” to complete the unlocking process.
You can now eject the SIM tray and remove the original carrier SIM and then insert the SIM card that you would like to use on your GSM iPhone 4S. The upper left corner will still display “no sim” or “no service” once you go back to the home screen but will change from “searching” to “Signal”. The signal bars should appear with 3 minutes.
