simpleSIM does not provide a truly unlimited data eSIM for French Guiana. While the plans are labeled “Unlimited, ” the data cap listed is 1 GB per day and a reduced speed of 512 kbps applies once that limit is reached, so the high‑speed data is not unlimited.
Travelers who need more data can choose from fixed‑data plans instead. For example, a 20 GB plan is valid for 30 days and costs $23.53, and a 10 GB plan is valid for 30 days and costs $11.20. These plans allow high‑speed data usage without a daily cap and can be more cost‑effective for most travelers.
