YonoSIM eSIM Data Plans for French Guiana

YonoSIM does not provide an unlimited data eSIM for French Guiana.
Instead, the provider offers fixed data plans such as the French Guiana 20GB 30Days plan, available for $17.99 USD and the French Guiana 10GB 30Days plan for $7.99 USD. Plans with a 10GB/day allocation are also available for 3, 5, or 7 days at higher prices, though these come with a reduced speed of 512 kbps. Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user expects to consume data beyond the plan’s cap.

YonoSIM does not offer any eSIM plans for French Guiana that include a local phone number or SMS capability. The available options are data‑only plans, so travelers will need to rely on Internet‑based services for voice and messaging. Popular VoIP applications such as WhatsApp, Telegram, and iMessage can typically be used over the data connection, but it is wise to verify that these services are not blocked or restricted in French Guiana before purchasing a plan.

YonoSIM provides 55 single‑country data plans and 25 multi‑country data plans that cover French Guiana. The single‑country plans range in price from about $1.99 to $1, 291.99 and offer data caps between 500 MB and 20 GB, with validity periods from 3 to 30 days. The multi‑country plans are priced within the same overall range and provide similar data caps, allowing travelers to use the same eSIM across several destinations while still accessing French Guiana.
