How the major eSIM sellers actually differ
Not a ranking. A record of what each seller published on its own site on the day we checked, with links so you can read the source yourself.

Kurz erklärt
- The biggest difference is not price but shape: some sell unlimited data priced by the day, others sell gigabyte buckets as we do, and the two do not compare directly.
- The thing worth reading first at any seller is the refund policy: the conditions vary a lot, from "the QR must never have been scanned" to a partial refund minus an administrative fee.
- Listed prices move, and at least one seller shows a different currency depending on where you browse from, so every figure here carries the date we checked it. Follow the link for today's price before deciding.

| Seller | Pricing shape shown on the page | Top-up on the same profile | Support channels and hours published |
|---|---|---|---|


| Seller | Japan, as listed | Europe, as listed |
|---|---|---|

Häufige Fragen
Why not just rank them?+
Because we sell eSIMs too, so any ranking we publish has our interest in it. What we can do honestly is record what each seller publishes, date the check, and link the source so you can read it yourself.
Is an unlimited plan really unlimited?+
Read that plan's own fair-use terms. Many unlimited plans on the market set a daily amount and slow the line beyond it, so check what speed the plan's documentation states after the threshold before treating unlimited as uncapped.
How often will this page be updated?+
We re-check on a cycle and change the stamped date each time. If you find a figure that no longer matches the seller's page, tell us through the corrections page; we will fix it and date the fix.
Should I just buy from whoever is cheapest?+
For a short trip with light usage, price is a reasonable tiebreaker. For a long trip, solo travel, or a trip with appointments you cannot miss, the refund terms and the way you reach a human when something breaks are usually worth more than a few dollars of difference.
