An S4 comes in 2 basic types - CDMA for Sprint and Verizon and GSM for AT&T and TMobile. The hardware is completely different, you can't use one on the other network. (It's not that it's not allowed, it's like using a food processor to watch TV. To a CDMA phone - which you have - GSM signals - like AT&T and TMobile - are just noise.)
