JamboSim eSIM Data Plans for Saint Barthélemy

JamboSim does not provide a truly unlimited high‑speed data eSIM for Saint Barthélemy. The plans labeled “Unlimited” give 3GB of high‑speed data per day and apply a reduced speed of 1000 kbps after that allowance is used. For travelers who need larger or truly unlimited usage, JamboSim offers fixed data plans instead, such as the 20GB 30‑day plan for $15.99 USD or the 10GB 30‑day plan for $9.99 USD. These options give a defined high‑speed data allowance and can be more cost‑effective than relying on a capped “Unlimited” plan.

JamboSim currently does not provide eSIM plans that include a local phone number or SMS capability for Saint Barthélemy. Travelers who need voice or text will need to rely on data‑only connectivity; popular VoIP and messaging apps such as WhatsApp, Telegram, and iMessage can usually be used over the data connection for calls and messages, but some destinations may block or restrict these services, so visitors should confirm that the apps they need will work in Saint Barthélemy before purchasing a plan.

JamboSim provides 12 single‑country plans and 24 multi‑country plans that include Saint Barthélemy. The single‑country plans vary in price from $1.99 to $125.99 and offer data caps between 200 MB and 20 GB over validity periods of 3 to 365 days, while the multi‑country plans cover the same price and data ranges but grant access in multiple destinations. In addition, JamboSim offers two distinct plan types: 7 daily data cap plans that limit the amount of data you can use each day, which is useful for light, short‑term users, and 29 fixed data cap plans that give you a set amount of data for the entire validity period. Prices and data limits fluctuate across these options, giving travelers a broad range of choices to fit different budgets and usage needs.
