Coverage CheckerAirport Wi-Fi, SIM vendors and eSIM arrival tips by IATA code — on the esimgomobile roadmap.
Airport connectivity by IATA code needs a live airport dataset (Wi-Fi details, SIM kiosks, eSIM arrival tips) that we can keep current — terminal moves and kiosk closures make static lists rot fast. The pre-departure eSIM advice above works today.
Get a planThe Airport Connectivity tool will answer the traveler's first question on touchdown: how do I get online at this airport? Enter an IATA code (NRT, JFK, DXB…) and get the connectivity picture: free Wi-Fi availability and how to join it, where the SIM/eSIM vendors and kiosks are, and the eSIM arrival tips that make landing seamless.
The core advice is timeless, and you can use it today: install your travel eSIM on Wi-Fi before departure so it activates the moment you land — no kiosk queues, no airport Wi-Fi roulette, no arrival-day roaming shock.
Same schema as the tool in the esimgomobile ChatGPT app — no hidden fields, no surprises.
| Parameter | Type | Required | What it means |

Planned for v2 — it needs an airport connectivity dataset (free Wi-Fi details, SIM kiosk locations, arrival eSIM tips) served from our backend, which doesn't exist yet. Airport facts change constantly (terminal moves, kiosk closures); we won't publish a dataset we can't keep current. Until then: this page is an honest roadmap note, and the pre-departure eSIM advice above is the timeless version.

Explainer
Tools are free and instant. They're the fastest way to turn a vague travel question into a concrete next step.
The pattern is always the same: tell the tool a little about your trip, and it does the research you'd otherwise do across ten tabs.
Explainer
Bookmark it — travel questions have a habit of returning at the worst moment.
Most travelers use Airport Connectivity once while planning and once on the road. Both visits take under a minute.
Explainer
The tool is only as good as its inputs — a rough date range beats a perfect one you never enter.
If a result surprises you, rerun with different inputs. Exploring the options is the point.
Explainer
Every tool result points somewhere useful: usually a plan that fits, sometimes a guide that goes deeper.
And if you'd rather talk it through, the Tele Agent answers the same questions conversationally, any time.
From here the path is short — pick a plan, check out through Amazon Pay, scan the QR code, and you're done.
