Samsung has added a region lock on its Galaxy Note 3, but a lot of folks including this site, took offense about something like this. Even unlocked models incorporated region lock of approved countries. Fortunately, folks at XDA have churned out a little app called RegionLock away which does away from this unwanted feature.
You can download it from here or if you are feeling generous, you can also download it from Play store. Latter costs few dollars, but you encourage the developer to work on similar projects in future. Chainfire is the man behind this amazing app. He has even made a video of it.
