Looking for an extremely simple method to SIM unlock your Samsung Galaxy S III? Look no further. An app is available from the Google Play Store that helps you unlock your device in the simplest way possible. This app only works with the Galaxy S III I9300 version for now, rather unfortunately, but is still good news for anyone who possesses the international version of Samsung’s flagship device.
For those who are unaware, unlocking is basically a process that allows you to free a device locked to a certain carrier, and use it with some other carrier instead; one that gets better signal reception or has lower rates, perhaps. For instance, you can unlock an iPhone locked to AT&T’s carrier and use it with some other GSM carrier. In this case, you can now unlock your Samsung Galaxy S III and use it with any carrier you wish to, other than the one it originally came with. Although some people would suggest simply calling up your carrier and asking them to unlock your device (which they should happily do, since you are required to keep paying till contract termination), that is most often not the case. This is where developers and modders save the day, as usual. And once again they have come to the rescue by making an extremely simple app available to unlock your shiny new Samsung Galaxy S III.
The app, named “Voodoo Galaxy S III SIM Unlock” is free of charge but requires root. When installed and used, it unlocks your phone’s baseband, enabling use with any carrier without restriction at all. It is in beta for now so it will probably improve later on.
Before you download the app and attempt to unlock your Samsung Galaxy S III, make sure your Samsung Galaxy S III is both model I93000 and rooted. To make sure your device is the GT-i9300 navigate to Settings > About device > Model Number on your Samsung Galaxy S III.
