eSimfly eSIM Data Plans for Saint Barthélemy

eSimfly does not offer a truly unlimited data eSIM for Saint Barthélemy. All plans that carry the word “Unlimited” in their name provide 3 GB per day, after which a reduced speed is applied, so they do not give unlimited high‑speed data.

If you need a fixed‑amount plan instead, eSimfly sells several options for Saint Barthélemy. For example, the Caribbean Islands 10 GB 30‑day plan offers 10 GB of high‑speed data for 30 days, and the Caribbean Islands 5 GB 30‑day plan provides 5 GB for the same period. These plans may be more cost‑effective for most travelers.

eSimfly does not provide eSIM plans for Saint Barthélemy that include a phone number or SMS capability. The available plans from eSimfly for this destination are data‑only, offering only an internet connection without inbound or outbound voice or text messaging services. Travelers who need communication features can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

eSimfly provides 6 single‑country plans and 6 multi‑country plans that cover Saint Barthélemy, for a total of twelve distinct options. The plans range in price from $6.90 to $59.64 and offer data across a spectrum of 1 GB to 10 GB, with validity periods between three and thirty days. eSimfly’s catalog includes both daily data‑cap versions, where the data allowance resets each day, and fixed‑data‑cap versions that deliver the same total data amount throughout the validity period.
