Is the iPhone Duo worth it over a regular iPhone?

Only if you specifically want a folding inner screen. A standard iPhone is lighter, cheaper and has a longer track record. The Duo makes sense for buyers who value the 7.6-inch display enough to accept first-generation risk.

Does the iPhone Duo have a physical SIM slot?

No. It is eSIM only, so you activate service through your carrier digitally. Check that your carrier supports eSIM before buying.

How durable is the folding screen?

Apple rates the phone IP68 for water and dust resistance, but foldable OLED panels and hinges wear with use. There is no long-term reliability data yet for this first-generation model.

Expect the phone and a USB-C cable; Apple does not include a charger. Confirm the exact contents with the store before ordering.

Only for heavy photo, video or offline media users. Most buyers are fine with 256GB or 512GB, which cost less.

When is the price likely to be lowest?

Foldables usually see their first meaningful discounts around major sales events or when a successor is announced. Compare the current price against its recent range before buying.
