MobileSIM eSIM Data Plans for Saint Barthélemy

MobileSIM does not offer a truly unlimited high‑speed data plan for Saint Barthélemy. The plans titled “Saint Barthélemy Unlimited data for X days” provide 3 GB per day and apply a reduced speed of 1000 kbps after that limit is reached, so the data is capped before complete throttling.

Instead, MobileSIM’s fixed data plans give larger high‑speed data allowances. For example, a 10 GB plan for 30 days is available at $39.00 USD, and a 20 GB plan for 30 days is offered at $49.00 USD. These options may be more cost‑effective than the unlimited‑name plans for travelers who need a larger data supply with consistent speeds.

MobileSIM does not offer an eSIM for Saint Barthélemy that includes a phone number or SMS capability. The provider’s Saint Barthélemy plans are data‑only, so travelers will not receive a local SIM number or direct SMS service. However, most modern messaging and voice applications such as WhatsApp, Telegram, and iMessage work over data connections and can be used for calling and texting without a traditional phone number.

MobileSIM offers 12 single‑country plans and 8 multi‑country plans for Saint Barthélemy. Most of these plans are fixed data cap offerings, while a smaller segment provides daily data caps; the pricing across all plans ranges from about $2.34 to $99.00, with data capacities spanning 200 MB to 20 GB and validity from 3 to 60 days.
