How To SIM Unlock Samsung Galaxy S for Free without Code

This method has been confirmed to work for many Samsung Galaxy S variants including Galaxy S I9000, T-Mobile Vibrant and AT&T Captivate. It utilizes a free app that guides you through SIM unlocking your Galaxy S Series Android device for free without having to enter any code at all! It is intended for SIM-locked GSM models only and not for CDMA ones like Verizon Fascinate or Spring Epic 4G.

XDA-Developers forum member helroz recently released this app that does one thing and does it well – SIM-unlocking any Samsung Galaxy S variant without the need for entering a code. That’s pretty much all there is to it, so let’s get on with the method.

Please note that this method will not work on Docomo Galaxy S.
