The straight talk sim should work without an unlock code. Provided you have an AT&T compatible sim card that they recently started using again. My phone is an AT&T locked s3 using a Net10 sim. Put it in and then go to the APN Settings, insert your settings, reboot and enjoy. Tracfone, straight talk and Net10 are all 3 one in the same company, I assume since that's how it works on Net10 it will work that way for you.
Although I don't know for a fact that you shouldn't have to be unlocked someone else who does run straight talk could maybe post up.
Sent from my SAMSUNG-SGH-I747 running S3Rx MJ2 bootloader MJB modem and it is smooth
