Buying ipHones online and ship to family in the Phils.

You can only purchase Apple products where you reside, Apple will not ship internationally, since they are sold regionally. It is possible for you to buy and receive the iPhones in the US, then ship it back out to the Philippines on your own. I wouldn’t recommend it though since first, iPhones in the US have eSIM so they will have to find a carrier that supports that there. Second, Warranty and AppleCare+ only apply to the region of purchase, so they would have to ship the iPhones back to America for service. It is always recommended to purchase your Apple products rather where you reside, so instead you should just send the money to them so they can purchase them on their own.

Apple does not ship internationally.

You could buy the 3 phones in the U.S. and ship them to your family, but you would have to make sure that the phones are unlocked and you would need to understand that the phones will have no warranty coverage in the Phils.

So, if the phones ever needed service, your family would have to ship them back to you in the U.S. for repairs.

Our advice is always to buy a phone in the country in which it will be used most of the time. It would be much better if you simply sent the money to your family in the Phils and they purchased the phones there.
