    How can I make my galaxy s4 use att. Samsung told me there are unlock codes I have to Get from Sprint. But I'm avoiding that I owe them, for good reason.

    How can I make my Sprint contract phone become a prepaid att phone

    Sprint uses a CDMA network and AT&T uses a GSM network so you can't.

    So there's no way humanly possible to to access the Sprint unlock codes without calling Sprint?

    Right....
    CDMA doesn't use Sim cards and GSM does, so they are not compatible.

    This is entirely possible. you need to sim unlock the device by either contacting sprint or following the xda guide/tool. once you have unlocked it put the att sim in and then follow the att/tmobile guide and youll have a sprint s4 on att/tmobile. youll need to edit the apn's to get data/mms working, and even then it will be 2g/3g/4g hspa+ youll get. sprints s4 does not have the right bands for att/tmobile 4glte, but it will at least be working :)

    I bought a used Sprint S4 that I now use with straight talk (AT&T) prepaid. I had to unlock it internationally first, then domestically. It took me many hours because I wasn't sure what I was doing but just like Shabby said, you'll get H+. Everything works including MMS. In my area its FAST but results may differ. I used this thread to unlock:
