JamboSim eSIM Data Plans for Sint Maarten

JamboSim does not offer a truly unlimited data eSIM plan for Sint Maarten. Their only plan with “Unlimited” in the name – Unlimited – 7 days – actually provides 3 GB of high‑speed data per day, after which the speed is throttled to 1000 kbps. This means the plan has a clear data cap and reduced speed once the limit is reached.

Instead, JamboSim offers fixed‑data plans for Sint Maarten that may better suit many travelers. For example, a 20 GB plan for 30 days costs $38.99 USD and another 20 GB plan for 365 days is $77.99 USD. A 10 GB plan for 30 days is available for $23.99 USD. Because these plans provide a set amount of high‑speed data without throttling, they can be more cost‑effective for users who consume data heavily.

JamboSim does not provide Sint Maarten eSIM plans that include a phone number or SMS capability; only data‑only eSIMs are available from the provider. Travelers who need voice or messaging can use internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection.

JamboSim offers a selection of plans in Sint Maarten, including 5 single‑country options and 18 multi‑country options. The plans range from as little as $1.99 to $82.99, with data caps that vary from 200 MB up to 20 GB and validity periods spanning 3 to 365 days. Some plans provide fixed data amounts while others operate on a daily data cap, and a few allow tethering with a reduced speed limit of 1000 kbps.
