What this means in practice
On iPhone, eSIM lives in Settings › Cellular › Add eSIM. This model has no SIM tray in any country: it works with eSIM only, including in mainland China, Hong Kong and Macao. It stores several profiles and keeps two eSIMs active at once, so a home line and a travel plan can run side by side.
Check your own device
A model list tells you what the hardware can do. It cannot tell you whether your particular unit is carrier-locked, or whether it is a regional variant sold without eSIM hardware. Run the free check on the phone itself — it reads the eUICC chip directly and answers in a few seconds.

Frequently asked questions
Does every iPhone Duo support eSIM?expand_more
Yes. The iPhone Duo carries eSIM hardware. Note: eSIM only worldwide · eSIM confirmed, not released yet (on sale 23 October 2026).
Can I use an eSIM and a physical SIM at the same time on the iPhone Duo?expand_more
There is no physical SIM slot at all: it runs two eSIMs at the same time instead.
How many eSIM profiles can the iPhone Duo store?expand_more
An iPhone stores eight or more eSIM profiles and keeps two of them active at the same time. A stored profile consumes no data and no battery.
Why does my iPhone Duo not show the eSIM option?expand_more
Three causes account for almost every case: the unit is a regional variant sold without eSIM hardware, the phone is locked to a carrier that has not provisioned eSIM, or the software is too old. The free check reads the chip directly and tells you which applies.
