MobileSIM eSIM Data Plans for French Guiana

MobileSIM does not offer a plan that provides unlimited high‑speed data for French Guiana. The products that carry the word “Unlimited” actually allow 3 GB per day and, after that limit is reached, the speed drops to 1000 kbps, so they are not truly unlimited. For travelers who need more data without speed reduction, mobileSIM offers fixed‑data plans that may be more cost effective. Examples include a 20 GB plan valid for 30 days at $40.00 USD, a 10 GB plan for 30 days at $25.00 USD, and a 5 GB plan for 30 days at $15.00 USD. These plans give a larger data allowance at a consistent speed for the entire validity period.

MobileSIM does not provide eSIM plans for French Guiana that include a phone number or SMS capability. The provider offers only data‑only eSIMs for that destination. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages.

MobileSIM lists nine single‑country data plans and seven multi‑country data plans for French Guiana. The plans are available in both fixed data amounts and daily data caps, offering users flexibility for short‑term or longer‑term stays. Prices vary between roughly $1.50 and $72.50, while data allowances range from 200 MB up to 20 GB, giving a broad spectrum of options for travelers.
