iPhone Duo · SIM, cellular & price

No SIM tray. Not in any market.

Buy an iPhone Duo in 8 different markets and not one of them takes a physical SIM card, not even China, Hong Kong or Taiwan, where the iPhone 18 Pro still ships a tray. You still get four physically different devices, only one of them receives mmWave 5G, and the same phone costs hundreds of dollars more in some markets than in others.

Compare two markets, prices included

We sample 8 markets only — United States, China, Hong Kong, Taiwan, Japan, Australia, United Kingdom, Germany. Other countries Apple sells in are not covered here.

Where should you buy it?

The cheapest market is the United States, at USD 1,999 for 256GB against GBP 1,999 in the United Kingdom, and it is the only one that receives mmWave 5G. Unlike the iPhone 18 Pro there is no SIM-tray trade to weigh, because every Duo is eSIM only in every market. What you give up buying abroad is local warranty and walk-in support. Compare the prices with care: tax treatment differs from market to market.
