eSIMCard does not offer a truly unlimited data eSIM for French Guiana. Every plan labeled “Unlimited” actually contains a fixed amount of high‑speed data. For example, the Unlimited eSIM Data For 1 Days in French Guiana supplies 1GB of data and, after reaching that limit, the speed is reduced to 500kbps. Other “Unlimited Plus” plans provide 2GB per day and reduce speed to 2000kbps once the allowance is used, so the data is not unlimited in the sense of no caps.
Travellers who need more data can choose from fixed‑capacity plans that offer larger amounts of high‑speed data. Handpicked examples include a 50GB plan valid for 30 days and a 100GB plan valid for 180 days. These plans give a sizeable data allowance without throttling after the limit, which can be more cost‑effective for users who consume a lot of data during their stay in French Guiana.
