MobileSIM eSIM Data Plans for Saint Barthélemy

MobileSIM does not provide a truly unlimited data eSIM for Saint Barthélemy. The plans that carry “Unlimited” in their name actually give 3 GB per day of high‑speed data and then reduce the speed to 1000 kbps once that daily limit is reached.

Travelers who need more data can choose MobileSIM’s fixed data plans, such as the 20 GB for 30 days or the 10 GB for 30 days options, which offer larger data allowances without the daily cap.

MobileSIM does not provide eSIM plans for Saint Barthélemy that include a phone number or SMS capability. Only data‑only eSIMs are available from this provider for the destination.

Travelers can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages. However, some destinations may block or restrict access to certain apps or VoIP services, so users should verify that the apps they rely on are accessible in Saint Barthélemy before purchasing an eSIM.
