Unlocking a Iphone 5s for international purposes?

I recently purchased the iphone 5s from sprint and i would like to send it to Honduras and put a chip in it from their local phone companies, so that it will pick up on their towers there. How can i do this?

You can unlock your iPhone by contacting your service provider or follow some procedures given in some websites. I found one tutorial in thetechbulletin.com and here is the link.

I don't think it possible to unlock sprint iphone, i heard that you put T-mobile sim on it without being unlocked. I don't know much about that because my iphone 5 was locked on att i unlocked via http://myattiphoneunlock.com
