Iphone delivery

The SE may get delivered within 9 days, but the trade-in will take much much longer, at least 2 weeks.

Best bet is to setup a purchase appointment at a nearby apple store and buy the SE directly there and make the trade in at that time as well.

Much quicker and easier.

Do note, that warranty on an iPhone is not international, and should you need any warranty service or repair you will need to bring the iPhone back to the U.S for service.

You can check the estimated delivery time here: Buy iPhone SE - Apple under the "Add to Bag" button. you will need to enter the deliver zip code for wherever you are staying.

If you go through the online process for trade-in yes, you are locked in to send it in via the mail in option.

You need to do the purchase and trade in process all together at the store at the same time and you get immediate credit on your purchase.

Whether you’re making a purchase or not, we’ve made it easy to trade in an eligible

device either in a store or online. Just answer a few questions

regarding the brand, model, and condition of your device. We’ll provide

an estimated trade-in value or a simple way to recycle it.

If you accept the trade-in estimate in the store, we’ll give you

instant credit toward a purchase or a gift card you can use anytime.

If you accept the trade-in estimate online when you purchase a new

Mac, iPhone, iPad, or Apple Watch, we’ll arrange for you to send us your

old device. Once we receive it, we’ll inspect it and verify its

condition. If everything checks out, we’ll credit your original purchase

method and send you any remaining balance on an Apple Gift Card by

Email.

You should wait until you are home to purchase. Apple will not ship internationally.

Keep in mind that if you buy a phone in the US, the warranty will ONLY be valid in the US.

I believe only certain stores in Florida have been reopened.
