eSIMCard eSIM Data Plans for Saint Barthélemy

eSIMCard does not provide a truly unlimited high‑speed data offering for Saint Barthélemy. All plans that carry “Unlimited” in the name actually grant a fixed allowance—either 1 GB per day or 2 GB per day. When that daily threshold is reached the connection speed drops to the reduced speed specified in the plan, such as 500 kbps for the 1 GB/day packages or 2000 kbps for the 2 GB/day packages. These throttled speeds are applied after the high‑speed data limit is exhausted, so the plans are not unlimited in a technical sense.

Travelers who need more data and want to avoid speed reduction can choose from fixed‑cap eSIMs that offer larger data sums. For example, the 50GB eSIM Data for 30 days plan costs $144.63 and provides 50 GB of high‑speed data, while the 20GB eSIM Data for 30 days plan is available at $64.22. Selecting such a larger fixed‑data plan can be more cost‑effective for users who require sustained bandwidth throughout their stay in Saint Barthélemy.

eSIMCard does not provide an eSIM for Saint Barthélemy that includes a phone number or SMS capability. The only plans available from eSIMCard for this destination are data‑only eSIMs. Travelers who need voice or messaging can use VoIP apps such as WhatsApp, Telegram, and iMessage, which work over the data connection.
