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 for French Guiana that includes a phone number or SMS capability. Only data‑only plans are available for that destination.

For travelers seeking voice or text communication, VoIP applications such as WhatsApp, Telegram, and iMessage work over the data connection and can be used for calls and messaging without a local phone number.

Silvy currently offers five single‑country data plans for French Guiana, with prices ranging from $3.90 to $35.90 and data caps between 1 GB and 20 GB. The plans are available for durations of 7 to 30 days and tethering is permitted on some options. No multi‑country plans are listed for this destination.
