JamboSim eSIM Data Plans for French Guiana

JamboSim does not provide a truly unlimited high‑speed data plan for French Guiana. The plans that carry “Unlimited” in their name give a fixed daily allowance of 3GB/day and, once that limit is reached, the speed drops to 1000kbps. The plans are available for 3, 5, 7, 10, 15, and 30 days, plus a 7‑day Caribbean plan that also covers French Guiana.

For travelers who need a broader data allowance, JamboSim offers fixed‑data eSIMs such as the 20‑GB plans valid for 30 or 365 days and the 10‑GB plan valid for 30 days, all of which include tethering and do not throttle speed after the data cap is reached. These options may be more cost‑effective for heavy data users compared to the unlimited‑name plans.

Yes, JamboSim provides eSIM plans for French Guiana that include a phone number and the ability to send SMS. The available plans range from 1GB for 7 days at $11.99 USD to 20GB for 365 days at $105.99 USD, with intermediate options of 2GB for 15 days, 3GB for 30 days, 5GB for 60 days, and 10GB for 180 days. All of these plans carry the dialing code +1, so the number is a U.S./Canada style number rather than a local French Guiana number. They allow outbound voice calls and outbound SMS messages; inbound voice and SMS are not supported.

Because the plan only supports outbound calls and messages, users who need to receive calls or texts would need to arrange alternative coverage. It is a good idea to confirm the exact calling and messaging functionality and any additional charges directly with JamboSim before purchasing.

JamboSim offers 9 single‑country plans and 24 multi‑country plans for French Guiana. The plans are divided into two main types: fixed data amount plans, which grant a set amount of data for the entire validity period, and daily data‑cap plans, which limit the amount of data that can be used each day. Prices range from $1.99 to $99.99, data caps span from 200 MB to 20 GB, and validity periods vary from 3 to 365 days.
