The iPhone 14 is the one where the SIM tray disappeared

Yes to eSIM. The tray is the real question

The iPhone 14 supports eSIM. That part is simple. The part that catches people out is the other half: the iPhone 14 is the first iPhone Apple sold in the United States with no SIM tray whatsoever.

Not a disabled tray. Not a tray you need a tool for. There is no slot in the side of the phone. The same iPhone 14 sold in the UK, the EU, Asia or anywhere else outside the US kept a physical SIM tray and works as a normal dual SIM handset.

So there are two different iPhone 14s in circulation, they look almost identical, and the difference decides what you can do on arrival in another country.

How to tell which one you're holding

Look at the edge of the phone. On a model with a tray there is a visible slot with a pinhole; on a US model there is nothing there at all. That is the whole test, and it is more reliable than trying to reason from where you bought it.

Where you bought it is a weak signal because handsets travel. A phone bought second-hand in Europe may be a US import. A phone bought in a US store and gifted abroad is still a US phone. The side of the case does not lie.

What "no tray" actually rules out

If you have the US version, one common travel habit is closed to you permanently:

• You cannot buy a physical SIM card at the airport, a phone shop, a supermarket or a kiosk and put it in this phone. There is nowhere for it to go.
• No adapter fixes it. There is no accessory, dongle or case that adds a SIM slot to an iPhone 14. The hardware simply isn't there.
• Borrowing a friend's spare SIM doesn't work either — same reason.

What remains is eSIM, in two forms: a travel eSIM you buy before you go, or a local carrier's eSIM if that carrier sells one to visitors. The second is not guaranteed. Plenty of local prepaid products are still sold only as plastic, and some that exist as eSIMs require a local ID or an app that expects a resident. Whether that applies where you are going is a country question — the country guides are where to check it.

If yours has a tray, you have both routes

Nothing here is a problem for you. Keep the home SIM in the tray, add a travel eSIM as the data line, switch data roaming off for the home line, and you have a reachable home number with data that doesn't come from your home carrier's roaming rates.

You also keep the fallback the US models lost: if a country guide says a local prepaid SIM comfortably undercuts the travel eSIMs, you can go and buy one.

The practical consequence for a US iPhone 14

Buy the plan before you fly, and install it before you fly. Installation needs a working internet connection, and on a tray-less phone there is no plastic-SIM plan B if it goes wrong at the far end. That is a change of habit rather than a hardship — but it is a real change, and it is the reason this page exists.

Sensible pre-departure sequence: confirm the phone is not carrier-locked, buy the eSIM, install it at home over wi-fi, check it appears in mobile data settings, then leave it turned off until you land.

Compare plans on the cheapest eSIM page, and confirm any other handset in the group with the eSIM phone checker — a travelling companion on an older phone may have entirely different options from you.
