Buying a SIM card at JFK Airport, New York

Where the counters are

Terminal 4 is JFK's main international terminal, and it is the only one where our data names a carrier-run counter: a T-Mobile kiosk in the arrivals hall. Beyond that, InMotion Entertainment — the airport electronics chain — has stores in Terminals 1, 4, 5 and 8. Our source also refers to a Best Buy kiosk in some terminals without naming which, so treat that as unconfirmed rather than something to plan around.

We hold no opening hours for any of these. Not for the T-Mobile kiosk, not for the InMotion stores. If you are landing late, do not build your arrival around finding one of them open.

For anything at JFK outside those four terminals, we hold nothing at all.

The queue has a specific bad window

The T-Mobile kiosk in Terminal 4 runs 15–20 minutes at peak, and the peak is the evening arrival bank — roughly 6pm to 10pm, when European and Middle Eastern flights land together. That is 15–20 minutes on top of immigration and baggage reclaim, at the end of a long-haul flight, standing in the busiest terminal in the country for international arrivals.

Outside that window we hold no figure, so we cannot tell you the wait is short at 11am. We can only tell you when it is reliably long.

No ID, about $20, and what that buys online

The United States asks for nothing to activate a prepaid SIM. No passport, no driving licence, no local address. Cash or a card, and you leave with a working SIM. That is genuinely unusual — most countries in our data require ID registration — and it is the strongest argument the counter has.

Our data holds a typical US airport SIM price of around $20. Here is what the same money buys as an eSIM bought before you fly, all read from the sellers' own sites on 13 August 2026:

The US ladder runs a long way up, and the top rung is the best rate in it: 50GB with 30 days of validity works out at $0.84 a gigabyte, less than a quarter of what the smallest plan costs per gigabyte. If you are in the country for a fortnight and use your phone normally, the large plan is not an indulgence — it is the cheap option.

One wrinkle. The US is one of twelve countries where Airalo sells two named tiers, Change and Change+. Every price above is Change. Change+ costs more at every size — $59 rather than $42 at 50GB — and we do not hold what the extra buys, so do not assume it is more data or better coverage.

Our eSIM Go rows are prices no traveller can pay, and our eSIMCard rows have been withdrawn after we read its site and found ours wrong. Neither belongs in the comparison above.

Nobody publishes the network — which changes the advice

Not one of the eSIM sellers we track for the United States — Saily, Airalo, eSIM Go, Nomad, eSIMCard — states which American network its plans use. That is not a gap in our research; the providers simply do not publish it. So there is no way to pick an eSIM at JFK on the basis of coverage, and any guide telling you to make sure you get a particular carrier is telling you to do something that cannot be done.

The counter is the one place where you do know. A T-Mobile kiosk sells T-Mobile service. If you have a specific reason to want one American carrier over another, buying from that carrier's own kiosk is the only route to certainty we can point you at.

The verdict, and getting into the city

At around $20, no ID and no appointment, the JFK counter is not a rip-off in the way some airport SIM counters are. It is simply beaten on price and on time by anything you install before you fly, and it is beaten worst at exactly the hour most international flights land.

Buy at the airport if your handset cannot take an eSIM — check the compatible phones list before you travel, not at the kiosk — or if a travel eSIM has failed to provision and you need to be reachable now. Otherwise install before departure and walk past Terminal 4's queue.

You will want data quickly either way. The AirTrain connects to Jamaica for the A, E, J and Z trains and to Howard Beach for the A, and from Jamaica the LIRR into Penn Station is the faster run. Full US pricing, coverage and the local-SIM comparison are on the USA hub.
