Carrier Switching carriers

[JacobK425]

So I have an iPhone 5 that was with AT&T and I was wondering if I could switch it to my Sprint carrier line that I have with my father?

No, you can't.

Sprint is a CDMA carrier. It does have LTE, which is GSM, but at the time of the iPhone 5 AT&T's model did not have the LTE bands that Sprint uses. Hence it won't work.
