Boost mobile iphone 5s unlocking?

So i'm buying a used iphone 5s for boost mobile and saw the unlocking is now available. So i was wondering how can i unlock it as i'm going to use it on boost but in june i'm traveling to guatemala and wanted to know if i could get it unlocked by that time.

You will have to have service for a full 12 months with a prepaid cell phone before they will unlock it for you. Some providers will not actually unlock the phones for you but give you credit towards the purchase of a new prepaid cell phone.
