The region lock is implemented in the form of a network blacklist. Beware that this is not exactly the same thing as a SIM lock, even though they are somewhat related. This blacklist blocks a number of whole countries and carriers, while a SIM lock whitelists one specific carrier. This app clears the network blacklist (region lock), but it may or may not remove the SIM lock, if present.One condition for you to use this app is to be rooted. However, if you don't have any intentions in rooting your device, you could buy a SIM unlock code for around $20, and this should also remove the region lock, though might not work in all the cases. Check out RegionLock Away on Youtube: You can download Chainfire's RegionLock Away from Google Play for a few dollars (this way you support the developer's work) or you could download it for free, RegionLockAway-v1.0.apk being provided by Chainfire himself.
