Yes · supports eSIM

Yes, the iPhone Duo supports eSIM. Two eSIMs can be active at the same time, and with a physical SIM the phone keeps two lines. A travel profile is installed at home over Wi-Fi; your own SIM stays in for calls and texts.

The earliest iPhone with eSIM in this catalogue is the iPhone XS, from 2018 — 8 years before the iPhone Duo. The iPhone 16e from 2025 has it too. Of its 2026 shelf-mates, iPhone 17e, iPhone 18, iPhone 18 Pro, iPhone 18 Pro Max carry the same answer.

The iPhone Duo is eSIM-only: Apple says it activates by eSIM only, the China mainland version (A3721) included.
