What to know about the iPhone Duo

iPhone Duo has no SIM tray in any country: it works with eSIM only and does not take a physical SIM card. It keeps two eSIMs active at once and stores eight or more, so your home number and a travel eSIM for data can run side by side.

Where are you taking your iPhone Duo?

It takes an eSIM, so you can buy a data plan now and install it before you fly. Pick your destination.

Check your own iPhone Duo

Two minutes on the phone itself settles it, whichever version you have.

  1. Dial *#06#

    Open the phone app and dial *#06#. If a number labelled EID appears, your phone supports eSIM.

  2. On an iPhone

    Go to Settings, then Cellular (or Mobile Data). If you see Add eSIM or Add Cellular Plan, it supports eSIM.

  3. Check it is unlocked

    A phone bought from a carrier on contract may be locked to it. Ask your carrier, or look for a Carrier Lock line in your settings that says No SIM restrictions.
