JamboSim eSIM Data Plans for Saint Barthélemy

JamboSim does not provide a truly unlimited data eSIM for Saint Barthélemy. The plans advertised with “Unlimited” in the name give 3 GB of high‑speed data per day; after that limit the speed drops to approximately 1000 kbps. The data cutoff is a hard cap rather than an open‑ended allowance, so travelers cannot use unlimited high‑speed data without throttling.

If you need a larger, unthrottled allocation, consider one of JamboSim’s fixed data plans for Saint Barthélemy. For instance, the 20 GB for 30 days product gives a generous amount of data at a single price, and the 10 GB for 30 days plan offers a smaller but still sizable bundle. These fixed‑data options can be more cost‑effective for travelers who anticipate high data usage during their stay.

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 offers 12 single‑country data plans and 18 multi‑country plans that include Saint Barthélemy. The plans come in two main styles: daily data‑cap options that limit usage each day, and fixed data‑cap options that provide a set amount of data for the whole validity period. Prices range from roughly $1.99 to $81.99, and data caps vary between 200 MB and 20 GB.
