Every eSIM plan in the partner catalog: provider, plan, data allowance, validity, and price, snapshotted weekly from the partner's live feed. Country rows carry an ISO code; regional and global multi-country plans have none (country_iso is empty). Plan-type distinguishes data-only from calls-and-texts bundles; stock status is the feed's own.

Each file states its own license: our derived datasets are CC BY-SA 4.0 (reuse with attribution, share alike), and the World Bank pass-through keeps its CC BY 4.0. Attribute as “TTDI” or “ttdi.net”, linking this page. Live event listings are deliberately absent — their upstream terms don’t permit raw redistribution, so we link them on city pages instead of dumping them here. Questions or corrections: the standards page has the process.
