Hello, I've had a galaxy S4 with sprint for a few months now, I've cracked the lcd twice now, im sick of this phone. What i am asking is if i can use a iphone 5 with the sim card in the galaxy as long as it would be under sprint. I need to know this!! I'll re word it for people who may be confused. Can i swap the sim card from a galaxy to a iphone 5 as long as its still sprint? thank you.
