JamboSim eSIM Data Plans for Martinique

JamboSim does not provide a true unlimited high‑speed data eSIM for Martinique. The only plans that carry “Unlimited” in their name are fixed‑data packages that allow up to 3GB of high‑speed data per day; once the daily limit is reached, speed is throttled to about 1 Mbps. Travelers who need higher data allowances can choose from JamboSim’s fixed data plans, such as the 20GB/30‑day plan or the 10GB/30‑day plan. These offer larger data totals without the daily cap, but they are still fixed‑data options rather than unlimited plans.

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.
