AeroSims eSIM Data Plans for French Guiana

AeroSims does not provide a true unlimited‑data eSIM for French Guiana.
The plans that carry “Unlimited” in their name are fixed‑data plans that deliver 5 GB of high‑speed data per day; once that 5 GB is used, the speed throttles to 512 kbps.

Travelers who need higher data volumes can choose AeroSims’ fixed‑data options, such as the Cayenne 20 GB / 30 days plan, the Cayenne 10 GB / 30 days plan, or the Cayenne 5 GB / 30 days plan, which provide a set amount of high‑speed data for the full 30‑day period.

AeroSims does not provide eSIM plans that include a phone number or SMS capability for French Guiana. Only data‑only eSIMs are available from the provider. Travelers who wish to make voice or text communications can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps are accessible in French Guiana before proceeding, as some destinations may block or restrict certain services.

AeroSims makes 11 single‑country data plans available for French Guiana and 3 multi‑country plans that include the territory. The plans span a price range from roughly $3.90 to $91.63 USD and a data cap range from 3 GB to 20 GB. Six of the plans feature a daily data cap, providing a fixed amount of data for each day, while eight plans offer a fixed data amount for the entire validity period, giving customers a set quota that does not reset daily.
