eSimfly eSIM Data Plans for Saint Barthélemy

eSimfly does not provide a plan with truly unlimited high‑speed data for Saint Barthélemy. The plans labelled “Unlimited” give 3 GB per day of high‑speed data and, once the daily limit is reached, the speed is throttled to 1000 kbps. Users who need more data can opt for the fixed‑cap alternatives available from eSimfly, such as the 100 GB 30‑day plan for $69.07 USD or the 50 GB 30‑day plan for $51.81 USD, both of which offer full‑speed data without daily caps. Choosing a fixed data plan can be more economical unless a traveller is an extremely heavy data consumer.

eSimfly does not offer a Saint Barthélemy eSIM that comes with a phone number or SMS capability. Only data‑only eSIM plans are available for this destination.

Travelers who need voice or messaging services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to certain apps or VoIP services, so it is advisable to verify that the services you rely on are accessible in Saint Barthélemy before purchasing a plan.

eSimfly offers 6 single‑country plans and 8 multi‑country plans that cover Saint Barthélemy. The available plans range in price from roughly $7.59 to $69.07 and in data limits from 1 GB up to 100 GB. Several plans use a daily data cap that limits the amount of data that can be used each day of the validity period, while other plans provide a fixed data cap that applies for the entire duration of the plan. All plans allow tethering, and a reduced speed option of 1000 kbps is available when speed is limited.
