Hello .... my question is ??? Can you sell an iPhone 7 or 7 plus that will serve me for metro PCS and how much would the value be? Thanks .. .

If I brought an I8 plus to Peru and it is released

Maybe you will not have the 7 or 7plus, but if you buy the complete cell phone (not financed) they will sell it to you unlocked and it can be used with MetroPCS

There is an Apple store, they sell you any released cell phone, they make you for any company in the world
