eSIM French Guiana: 5G/4G for Cayenne & the Kourou Space Centre

Welcome to French Guiana, a unique department of France nestled in South America. Whether you are in Cayenne for business, or in Kourou for a mission at the Guiana Space Centre (Centre Spatial Guyanais), a high-speed, reliable data connection is non-negotiable.

Stay connected in this high-tech jungle with Cellesim's French Guiana eSIM plans, starting at just $5.29. Choose from 7 limited and 14 unlimited plans.

CRITICAL: Avoid the "South America" Roaming Trap

IMPORTANT WARNING: While technically part of France, French Guiana is in South America. For most non-EU carriers (from the US, UK, Canada, Asia, etc.), this territory is NOT included in any "European" roaming plan.

Your home carrier will charge you astronomical "Rest of World" or "South America" roaming fees, often per-megabyte. An eSIM for French Guiana is the only smart, cost-effective way to get data. Get connected the moment you land at Cayenne – Félix Eboué Airport (CAY).

Why Cellesim is Essential for Your Trip to French Guiana

• Instant (CAY) Airport Connection: Get online the moment you land at (CAY) Airport. This is critical for coordinating transport or contacting your team in Kourou or Cayenne.
• Massive Cost Savings: Our plans start at $5.29. This is a fraction of what you would pay for just a few megabytes of high-cost roaming.
• Keep Your Home Number: Your eSIM handles the data, so your primary SIM (and your WhatsApp number) remains active for important calls and texts.
• Premium 5G/4G Speed: As this is an EU territory, the infrastructure is strong. Connect to top-tier 5G/4G networks (like Orange Caraïbe) perfect for business needs.
