Q: hi there! my name is rose thayer and I live in Guam and planning to buy an iphone 5s but im wondering if its possible to ship it in Guam?

I wish I lived in Guam

The last time I went to the online Apple store in Australia there was  afeature where you could chat to an Apple rep.  Why not see if that is something you can do and if so ask the rep if Apple ships to Guam

I asked Apple in the online chat thing I mentioned and they said they only ship withint the country where the purchase is made.  Isnt Guam part of the US? Maybe they thought I was in Australia and wanted to ship to Guam. why dont you go to the US apple site and pretend that you are buying a phone and then the chat section will appear at the top of the window and ask the question yourself

look at this https://www.apple.com/asia/iphone/buy/guam.html

I suppose you could have someone buy an unlocked one from an Apple store in the US and ship it to you but the warranty only applies to the country where the phone is purchased

It is up to the carrier to support unlocking.  GTA doesn't according to the kBase article.
