As I mentioned though you could not take your verizon s4 and expect to use it under straight talk/verizon towers, they dont let those phones on the network.Not a bad deal for $45. I've seen t-mobile and AT&T Sims but didn't know they had all 4. Nice.
They limit the cdma byod to old 3g only phones. Or at least they did, but heck this could have changed too.
Though from what I have been reading the verizon s4 does have both att and t mobile gsm frequencies, so you could technically put a att sim into the verizon s4 and run straight talk on it.
