Technically no, they are not the same. However if you did find a way to Sim unlock, it would work overseas too.
I'm guessing you're looking for a free way to Sim unlock your phone. And as far as I know there is none. However people have had success with Chainfire's
RegionUnlock. It may or may not work I can't say, I don't even have a usable sim card to test it for you. But you have to be ROOTED for it to work. I hope I helped.
