eSIMCard does not provide a truly unlimited high‑speed data plan for French Guiana. All plans advertised as “Unlimited” actually specify a daily data cap—most commonly 1 GB per day or 2 GB per day—after which the speed drops to a throttled rate of 500 kbps or 2000 kbps. These plans are labeled unlimited in the marketing name but are not unlimited in consumption.
Travelers who need more data can choose from eSIMCard’s fixed‑data options, such as the 50 GB plan for 30 days or the 35 GB plan for 30 days, both of which provide a set high‑speed allowance without throttling. Selecting a fixed data plan can be more cost effective unless the user is a very heavy data consumer.
