MobileSIM eSIM Data Plans for Saint Barthélemy

MobileSIM does not provide a truly unlimited high‑speed data eSIM for Saint Barthélemy. The plans marketed as “Unlimited” actually allow 3GB of data per day, and once that daily limit is reached, the speed drops to 1000 kbps. Thus the name does not reflect unrestricted high‑speed use.

Instead, MobileSIM offers fixed data plans that can be more cost‑effective for heavy users. For example, a 20 GB plan valid for 30 days is priced at $49.00, and a 10 GB plan for the same period costs $39.00. These plans deliver larger data allowances without the speed reduction applied after a daily cap.

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 data plans and 7 multi‑country data plans for Saint Barthélemy. The available bundles span a price range from $1.50 to $99.00 and data caps between 200 MB and 20 GB. Among these, fixed data plans provide a set amount of data for the entire validity period, while daily data‑cap plans cap the data usage on a per‑day basis, letting users manage daily consumption more tightly.
