Source and method
Figures come from the TripoSIM travel eSIM dataset (CC BY 4.0), generated from TripoSIM's live catalog on 2 November 2026: country-level observed price fields in USD, which do not verify a purchasable plan for a specific trip. Rankings compare the median price per GB across observed catalog entries in each country. This site is owned by the same company as TripoSIM, so this is first-party data, not an independent market survey. Prices, plan duration and individual terms can change; the checkout page is authoritative. A country-level network list can combine different SKUs, not networks guaranteed in any one purchased profile.
