You can't from what my mom told me....my mom owns an Iphone and they went to the official metro pcs store...to see if they would activate it and they said they can't....it seems like the phone is too high tech for there company
I think you can if you flash it but it would cause a lot of money
Totally different technology
Because I iphone use sim network
and metro pcs use different network
and metro pcs use different network
