How to use AT&T S4 on International Network??

Hi guys one of my friends bought a S4 in the US, It's AT&T locked SGH-I337 so can't use it with sim in our country (South Africa)We have two models of S4 here, the I9500&I9505. Was wondering what the right steps is to get the phone working? Must I root the phone and flash custom Rom & kernel or just unlock sim card? I'm not new to Rooting or flashing Roms but haven't fidled with carrier locked phones before [emoji3] [emoji2]
Send from my UNBENDABLE NOTE 3 ?
