eSIMCompare reads every provider's own catalogue and compares the plans by what a trip actually costs. Every price is cited to its source and dated, and every figure on the site links to the record that proves it.
Buying data for a trip means choosing between dozens of eSIM providers that sell the same gigabytes in different shapes: different allowances, validity windows, daily speed caps and prices. Their own pages are built to sell one brand, so the questions a traveller has (which plan covers my trip, what does a gigabyte really cost, what happens after the daily cap) are hard to answer side by side.
eSIMCompare puts the plans next to each other under one set of rules, ranks them by the cheapest plan that covers a typical trip, and shows the per-gigabyte price and the speed policy beside every one.
Each provider's plans are read from a source we can re-read ourselves: its partner feed or API, or its public plan pages. Prices are re-checked on a schedule, labelled Verified or Reported, and dated, so you can see how fresh each one is. The rules are written out in the methodology, and the whole catalogue is published as an open dataset.
When a provider runs an affiliate program and we have joined it, its buy links carry the program's tracking, and we earn a commission if you buy. You pay the provider's own price either way. Every tracked link says so beside it, and the methodology names every provider that pays us.
In the recommended order, a provider whose program pays us gets a disclosed partner boost, worked out by one formula for every provider. It never changes a price, and lists ordered by price alone ignore it. Rank, placement and reviews are never for sale (how listings work).
eSIMCompare was founded by Yuma Heymans, who also writes its guides. Much of the day-to-day work (reading providers' catalogues, re-checking prices, building the comparisons, answering providers) is done by software and an AI operator under his direction. That is why every figure is linked to its record: nothing here asks to be taken on trust.
Our figures are free to quote with a link back. The travel eSIM price index gives what a week of mobile data costs in each country, our monthly report Travel eSIM Prices, October 2026: 18,332 Plans Compared reads them region by region and provider by provider, the open dataset has every plan with its source and date, and AI agents can query the same data live over MCP. The numbers most often quoted, with their sources, are on our travel eSIM statistics page. For a figure we do not publish, write to us below.
