MobileSIM eSIM Data Plans for Saint Barthélemy

MobileSIM does not provide a true unlimited data eSIM for Saint Barthélemy. Its plans that use “Unlimited” in the name are limited to 3GB each day; once that amount is reached the connection is reduced to 1000kbps. If a traveler prefers no speed reduction, MobileSIM offers fixed‑data plans such as 20 GB for 30 days at $49.00 USD and 10 GB for 30 days at $39.00 USD, which may be more cost‑effective for heavy data users.

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.
