All providers we track
What it takes to appear here
Every provider below has a live catalogue connected to our comparison engine. We pull their plans and prices through automated feeds, compute the real price per GB for every plan, and rank them against every rival in every country they cover. Listing is free and cannot be bought. Money buys nothing here: not a listing, not a position, not a star.
This page updates itself. When a new provider's catalogue is connected, their card appears below automatically with live numbers, and their plans start competing in every relevant country table the same day.
Providers on eSIM Watchdog right now
Quality over quantity
Directories that list two hundred sellers usually cannot verify any of them. We only compare catalogues we can check properly, with machine readable prices we can re-verify at every sync. That keeps every number on this site backed by a timestamped check instead of a screenshot from last month. More catalogues are being connected, and each one goes through the same wiring before it appears.
Run an eSIM service? Get compared.
If you sell travel eSIMs and want your catalogue in our comparisons, tell us about your service on the list your service page. We need a machine readable feed of your plans and prices. Listing is free, we review every application by hand, and your plans will be ranked by exactly the same maths as everyone else, including the providers who pay us commissions.
