For Saint Barthélemy, esim0 provides 30 single‑country plans that cover just the island, plus 6 multi‑country plans that include it within a broader regional package. The single‑country offerings range in price from about $1.99 up to $197.99, with data limits from 1 GB to 20 GB and validity periods from 1 day to 365 days. The same price and data ranges appear across the multi‑country plans, although the specific data cap may differ slightly due to regional bundling.
Plans that list a “daily data cap” provide a fixed amount of data for each day (e.g., 1 GB per day), while those with a “fixed data cap” give the buyer a set amount of data for the entire validity period (e.g., 5 GB for 30 days). Both types appear among the 21 daily‑cap and 15 fixed‑cap options in the overall catalog.
