JamboSim eSIM Data Plans for Saint Barthélemy

JamboSim does not provide a truly unlimited high‑speed eSIM plan for Saint Barthélemy. Their plans that carry the label “Unlimited” actually allocate 3 GB per day and enforce a reduced speed of 1000 kbps once the daily quota is reached, so they are capped in data amount.

Instead, JamboSim offers fixed‑data plans for the destination, such as a 20 GB plan valid for 30 days priced at $14.99 USD and a 10 GB plan valid for the same duration priced at $10.99 USD. These options give a larger data allowance before any throttling, which can be more cost‑effective for travelers who need consistent high‑speed connectivity.

JamboSim does not provide eSIM plans for Saint Barthélemy that include a phone number or the ability to send or receive SMS. All available JamboSim plans for this destination are data‑only, offering internet access without built‑in voice or text services.

If you need to make calls or send messages while on Saint Barthélemy, you can use popular VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection provided by the JamboSim eSIM.

JamboSim offers 12 single‑country data plans for Saint Barthélemy, with prices ranging from about $1.99 to $82.99 and data allowances from 200 MB up to 20 GB. In addition, 18 multi‑country plans that include Saint Barthélemy are available, which cover the same broad price and data ranges. The provider differentiates between fixed‑data‑cap plans and daily‑data‑cap plans: a fixed‑data plan supplies a set amount of data for the entire validity period, while a daily‑data plan resets the data cap each day throughout the plan’s duration. These plans also allow tethering and offer a reduced speed option of 1000.
