MobileSIM eSIM Data Plans for Saint Barthélemy

MobileSIM does not provide a truly unlimited data eSIM for Saint Barthélemy. Its “Unlimited” plans give a daily allowance of 3 GB and after this limit is reached the speed is throttled to 1 000 kbps, so the data is not limitless. Travelers looking for a fixed high‑capacity plan can choose options such as 20 GB for 30 days at $49 USD or 10 GB for 30 days at $39 USD, which offer higher data volumes without the daily restriction. These fixed plans may be more cost effective for users who need consistent high‑speed data throughout their stay.

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.
