The account wasnt/isnt in your name sprint wont give you the unlock code for it even if she had it active that long. She will have to call. Also at least with the htc one with sprint its not just a matter of unlocking the sim card for it to work on u.s. gsm networks. The sprint htc one was a pain in the butt to unlock once they updated it. Now not sure about the s4 but sprint has a history of locking down the gsm radios in there devices not to be used on native gsm towers.
That isn't legal at least in Verizon's case
They aren't allowed to that anymore
