Doesn't work. Someone is just rehashing what worked on older galaxy phones. I think it worked for S4 and they just assume it will work for Note 3.
This isn't the first site to post this. I believe it requires being on 4.1 if I remember correctly. Check the domestic unlock thread, I believe someone posted the same thing there. @Epix4G
, you even commented the post in the domestic unlock thread
