JamboSim eSIM Data Plans for Martinique

JamboSim does not provide a truly unlimited data eSIM for Martinique.
The plans labelled “Unlimited” give a 3 GB/day allowance, after which the speed drops to 1000 kbps; thus the high‑speed data is capped. If you need more data without such throttling, you can choose one of JamboSim’s fixed‑data plans—for example a 20 GB plan valid for 30 days or a 10 GB plan also valid for 30 days. These options give larger, uncapped data allowances and may be more cost‑effective for heavy data 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.
