Steps
Ask your carrier for an eSIM for your number. They will email or hand you a QR code, or send activation details you can enter manually.
Connect the iPhone Duo to Wi-Fi and make sure it is unlocked and signed in to your Apple ID.
Open Settings, then tap Cellular. If you are moving from an old iPhone, tap Add eSIM and choose Transfer from nearby iPhone.
To use a QR code instead, tap Add eSIM, then Use QR Code, and point the camera at the code your carrier gave you.
If you have no QR code, tap Enter Details Manually and type the SM-DP+ address and activation code from your carrier.
Wait while the iPhone Duo downloads the eSIM profile. Keep the phone on Wi-Fi and do not close the Settings app.
Label the new line, for example Personal or Work, and choose whether it is your main line for calls, messages and data.
Repeat the same steps with a second QR code to add a second line. Two active eSIMs let you run both numbers at once.
Open Settings, Cellular and check that the line shows as active. Turn on Data Roaming only if your carrier tells you to.
Make a test call and send a text to confirm the eSIM is working before you leave the carrier store or wipe your old phone.
Tips and common mistakes
QR codes from carriers usually work only once, so request a new one if the scan fails.
Keep the old phone and SIM active until the eSIM shows signal, in case the transfer needs to be repeated.
Each eSIM line needs its own carrier plan, so confirm the second line is activated and billed correctly.
Never share your eSIM QR code, as anyone who scans it can activate your number.
Questions
Can I use a normal plastic SIM card in the iPhone Duo?
No. There is no tray or slot, so the phone only accepts eSIM profiles. Your carrier must support eSIM to give you service.
How many eSIM lines can I add?
You can store several eSIMs, but only two lines can be active at the same time. Extra lines stay saved and can be switched on later in Settings, Cellular.
What if the eSIM does not activate?
Check that you are on Wi-Fi, that the QR code has not expired, and that the phone is carrier unlocked. Then call your carrier to reissue the activation details.
