However, sometimes it says the unlock was unsuccessful but after a reboot you may still find yourself unlocked.
1- Go to “Android Market”, download [Root] Galaxy S2 SIM Unlock and Install the application.
2- After it finishes the downloading and Installation, Launch the application, Press the “SIM unlock code” button, wait for few minutes and it will come up with a code.
