Our mission

eSIM Metric exists to make mobile data abroad simple and cheap. We collect plan catalogs and public prices from licensed eSIM providers, normalize them into one comparable table, and point you straight to the official checkout.

How the data works

Prices and plan details are pulled from the official public feeds of each provider (currently Airalo and GigSky) and refresh automatically every day. Prices are shown in USD. When a provider runs a promotion, we display both the theoretical list price (struck through) and the actual discounted price.

We never invent data. If a plan has an unknown data size, it is shown as a dash instead of a guess.

Independence

Rankings such as "Best Value" are computed algorithmically from the price-per-GB and the total price of each plan — not from commission size. See our Affiliate Disclosure for the business model, and Terms of Service for the rules that govern this site.
