Purchasing iPhone in One Country and Using it in a Different One

Almost every week I see people asking whether it is possible to use an unlocked carrier-free iPhone purchased in one country (USA, UK etc.) in a different country. In order to make things clear, I've converted one of such threads to a user tip.

Thanks Bznzman for asking the question and imobl for adding important details. The link to the original thread is available below.

Hi Apple support,

I am wondering if it is possible to buy an iPhone 6s in Taiwan and use it in Europe (The Netherlands).

The voltage divers in both countries where the Dutch use 230v and Taiwanees 110v.. Would there be any problem charging the purchased phone in the Netherlands?

It is possible to buy iPhone in one country and use it in another, however, you need to keep in mind that the warranty is valid only in the country of purchase.

In addition to the warranty issue pointed out above, some features such as 4G/LTE may also not be available when purchasing an iPhone in one country to use in another.

FYI: If you buy your iPhone in any nation member of the EU, your warranty will be valid throughout the EU. And all features will be available when using a supported wireless provider.
