Silvy eSIM Data Plans for French Guiana

Silvy does not provide an unlimited data eSIM for French Guiana. The available plans give fixed data allowances, such as 20GB for 30 days or 10GB for 30 days, each at a set price and validity period. These fixed plans, which include tethering and 5G service within French Guiana, are the only options for travelers. Selecting a fixed‑data plan can be more cost effective unless a traveler is an extremely heavy data consumer who would otherwise need a higher‑capacity solution.

Silvy does not provide an eSIM plan for French Guiana that includes a phone number or SMS capability. Only data‑only eSIMs are available from this provider for the destination. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but it is advisable to confirm that these services are accessible in French Guiana before making a purchase, as some destinations may block or restrict certain apps.
