Yesim eSIM Data Plans for Saint Barthélemy

Yesim does offer unlimited data eSIM plans that cover Saint Barthélemy. Two 1‑day unlimited options are listed: a Saint Barthelemy plan for $13.70 USD and a Caribbean plan for $20.54 USD. Both plans allow tethering and state that speeds may be throttled after high‑usage periods under a Fair Usage Policy. If a user is concerned about potential speed restrictions or wants to confirm how much data can be used at normal speed, they should contact Yesim directly to verify the details.

Yesim does not provide an eSIM with a phone number or SMS capability for Saint Barthélemy.
Only data‑only eSIM plans are available from this provider. Users can still communicate through the internet using VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection without requiring a local phone number or SMS service.

Yesim lists ten packages for Saint Barthélemy, divided evenly between single‑country and multi‑country options. The five single‑country plans provide fixed data amounts from 1 GB to unlimited over 1 to 30 days, while the five multi‑country plans give the same data spectrum but are valid across all supported destinations. Prices range from approximately $12.33 to $112.99 USD, and the plans can include tethering with possible speed throttling. If a plan is marketed as a daily‑cap plan, its data is refreshed each day; otherwise the plan offers a single, all‑in‑one data allowance for its validity period.
