Installation Guide
Install whichever plan you pick, in minutes.
Open toolEnter your itinerary. Get a straight recommendation: single-country, regional, or global plan — with the reasoning shown.
Three countries in Europe? One regional plan beats three local ones. Europe plus Japan? Now you want global. This tool maps your itinerary to regions and recommends the plan type that covers the trip with the least juggling — and shows its work.
Type your countries separated by commas. The tool maps each to a region and recommends single-country, regional, or global.
Every recommendation ships with its “why” — which regions your trip spans and why that points to the plan type.
Whichever type you pick: install on Wi-Fi before departure so the plan activates on landing, not after a SIM-shop queue.
Pure itinerary logic — no signup, no tracking, runs entirely in your browser.
List the countries you’re visiting, separated by commas. The recommendation uses our published region lists.

Tip: install the eSIM on Wi-Fi before departure so it activates on landing.
In the esimgomobile ChatGPT app and API, this tool is called with exactly these parameters — nothing hidden, nothing invented.
| Parameter | Type | What it is |
|---|---|---|
countries | array of string (min 1) | Countries on the itinerary, e.g. [“France”, “Italy”, “Japan”]. |
This tool recommends a plan type, not a specific plan or price — it’s itinerary logic, not a catalog. Region mapping covers the most-traveled countries; anything else maps to “Other” and nudges toward global. At launch, the recommendation will link straight to matching esimgomobile plans; until then, it’s the honest pre-purchase guidance it claims to be.

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.

From here the path is short — pick a plan, check out through Amazon Pay, scan the QR code, and you're done.
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.
