Delivery to Malaysia

Apple does not do international shipping. You can personally buy a phone and then personally ship it if you want to.

Yes you can do that, but there are some regulations that are specific to some countries that may spoil your experience with Apple products.

For instance, ECG app cannot be used on wearable devices in UAE, so if you buy Apple watch from there and take that watch to some other country you would not be able to use the ECG app.

And you can claim the warranty only in the country of purchase.

I hope this helps!

Yes. The warranty will only be available in Singapore.
