eSimfly eSIM Data Plans for Saint Barthélemy

eSimfly does not provide a true unlimited high‑speed data eSIM for Saint Barthélemy. The plans that use the word “Unlimited” offer 3GB per day; once that daily limit is reached, the speed is throttled. This means the amount of high‑speed data is still capped, though the name may be misleading.

If travellers need more data, eSimfly sells fixed‑data plans that grant a larger, non‑throttled allowance. Examples include a 20GB plan valid for 30 days and a 50GB plan valid for 30 days, both of which provide the full data quota without reduction. These fixed plans can be more cost‑effective when a higher total data amount is required.

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.

The service provides 19 single‑country plans for Saint Barthélemy and 12 multi‑country plans. Plans are priced between $4.42 and $183.26 and give between 1 GB and 50 GB of data, valid from 3 to 365 days. Some offerings are fixed‑data, giving a set data amount for the full validity period, while others are daily‑cap, limiting data usage on a per‑day basis.
