JamboSim eSIM Data Plans for Martinique

JamboSim does not provide a truly unlimited data eSIM for Martinique. The plans labeled “Unlimited” actually allow 3 GB per day of high‑speed data; once that daily quota is reached the speed is throttled to 1000 kbps, and the plan name is marked as havingUnlimitedName = true. Therefore the data is not unlimited in the sense of no restriction on quantity.

Instead, JamboSim offers fixed‑data options such as the 20 GB / 30 days plan priced at $17.99 USD. This plan offers a larger, unthrottled data allowance for a set period, which can be more cost‑effective for travelers who need a sizable amount of data but are not extreme heavy users.

JamboSim sells eSIMs for Martinique that include a phone number on the dial‑code +1, allowing outbound voice calls and outbound SMS. The plans range from 1GB data for 7 days at about $11.99 USD up to 20GB data for 365 days at around $105.99 USD. Validity periods are 7, 15, 30, 60, 180, or 365 days depending on the chosen data cap.

Because all available packages provide outbound only telephony, users who need inbound call or SMS reception should confirm the details directly with JamboSim before purchasing.

JamboSim offers 12 single‑country data plans and 18 multi‑country plans for Martinique. The plans cover a price range from about $1.99 to $106.99 and provide data caps between 200 MB and 20 GB, with validity periods from 3 to 365 days. Some offerings feature daily data caps, while others provide fixed data amounts.
