AeroSims eSIM Data Plans for French Guiana

AeroSims does not provide a truly unlimited data eSIM for French Guiana. The plans that carry the “Unlimited” name give 5 GB of high‑speed data per day and then throttle speed to 512 kbps once that daily limit is reached, so the data allowance is still capped.

If you need a larger, fixed data allowance, AeroSims offers several fixed‑data plans for French Guiana, such as the Cayenne 20 GB/30 days, Cayenne 10 GB/30 days, and Cayenne 5 GB/30 days options. These plans provide a set amount of high‑speed data that must be used within the 30‑day validity period and can be more cost‑effective for most travelers unless you are an extremely heavy data user.

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.
