Hello and welcome ddice - thanks for joining Android Forums!!
I am not familiar with the SGS III - the best place for you to start would probably be in the Samsung Galaxy S3 - Android Forums
sub-forum. When I got my Desire HD, I rooted and, as part of the process, the phone was SIM unlocked... I would imagine that something similar would be done with your phone - one of the other users of your phone would be able to advise.
If you wanted to go down the rooting path, then you would be able to discuss it with other owners of the SGS III, who would point you in the right direction.
As an alternative (because rooting is not for everyone), could you try putting a SIM in that is from your country, rather than a foreign one? This way, you may get prompted for an unlock code?
Hope you find this place useful!!
