Buying a US iPhone Duo from abroad: eSIM only, so check your carrier first
Short answer: every iPhone Duo we sell is the US model, eSIM only (no physical SIM tray). Works on carriers that support eSIM; check yours before buying. So the question that matters for a buyer outside the US is whether your carrier can issue you an eSIM. Ask your carrier before you pay. We ship the iPhone Duo from Utah, USA with free tracked shipping to the destinations listed at checkout, within 2 business days of confirmed payment.
Step 1: Check that your carrier supports eSIM
There is no physical SIM tray, so you can't insert a plastic SIM card. Your carrier has to issue you an eSIM. Carriers usually do that by QR code, through their app, or by converting your current line in the phone's settings. Many carriers offer eSIM; some prepaid and smaller carriers don't.
Ask yours directly: "Can you put my number on an eSIM for an iPhone Duo?" Also ask whether the plan you want works with this model. A carrier offering eSIM does not, by itself, mean every plan or network will work with this phone, and we can't promise support for any particular carrier or country. If your plan needs a physical SIM, this US model is not the right fit.

Step 3: Understand delivery from the US
We ship from Utah, USA within 2 business days of confirmed payment, with free tracked shipping. Outside the US, delivery typically takes about 6–10 business days after dispatch and varies by destination. International parcels go through customs clearance in the destination country, which can add time to delivery. In a few countries, imported phones also have to be registered with a regulator, so check your country's rules. Use an address where someone can receive the parcel, and include a phone number. We email your tracking number when the label is created. Times are estimates, not guarantees.
Step 4: Pay
At checkout you can pay by card or crypto (BTC, ETH, USDC, USDT or SOL). Each storage size costs the same either way.
Step 5: When it arrives
Check the phone against its listed condition: open-box, never used. The box has been opened, so we do not sell it as factory-sealed. The box holds the phone and a USB-C cable, with no power adapter, so use a USB-C charger you already have. Then add your eSIM.
Not right for you? The 30-day money-back guarantee covers any reason, including changing your mind; the steps are in our shipping and returns policy. Sending a phone back from abroad costs you return postage, so checking eSIM support first is cheaper.
