It is a neutral market index — Simsima is excluded from the median — published as open data under CC BY 4.0 (reuse allowed, including commercially, with attribution and a link to the source).\n\n- Global median: about $3.50 per GB; country medians range from ~$1/GB (e.g. Svalbard, Thailand, Bulgaria) to several hundred $/GB in remote territories (e.g. Niue, Tuvalu, Wallis and Futuna).\n- Median (not average) to resist outliers; updated daily with plan-by-plan price history.\n- Includes a world map, cheapest/most-expensive country rankings, a median-price-per-provider trend chart, and per-country pages.\n- Free developer API (keyless): `GET https://api.simsima.io/api/price-index/summary`, `/export.csv`, `/export.json`, `/providers`. A free API key unlocks the depth tier (`/v1/history`, `/v1/plans/{country}`).\n- Attribution required for reuse: \"Simsima eSIM Price Index\" with a link to https://simsima.io/en/esim-price-index\n\n## How to buy a Simsima eSIM\n\n1.
