From booking a last-minute boat tour on the Maroni River to checking real-time launch schedules at the Guiana Space Centre, constant connectivity transforms your experience. A digital eSIM activates before you even collect your luggage, giving you a crucial advantage in this land of contrasts.
Forget about fumbling with tiny plastic cards. An eSIM offers distinct benefits tailored for exploring French Guiana's diverse landscapes:
While French Guiana is part of the EU for some regulations, roaming charges from non-EU providers can be astronomical. A prepaid eSIM gives you transparent, upfront pricing with local rates, so you can freely share photos of the Amazonian canopy or live-stream a Ariane rocket launch without financial anxiety.
This technology is a game-changer whether you're a scientist visiting the spaceport, a birdwatcher in the Réserve Naturelle des Marais de Kaw, or a business professional with meetings in Saint-Laurent-du-Maroni. Reliable data means reliable plans.
Mobile infrastructure here is robust in populated areas, supporting both daily life and the high-tech space industry.
Our partnered providers ensure excellent connectivity where you'll spend most of your time:
For deep jungle expeditions near Saül or Maripasoula, always download detailed offline maps beforehand, as coverage becomes sporadic.
You'll enjoy swift 4G speeds in towns, perfect for video calls home or uploading HD photos. While 5G is emerging in central Cayenne, widespread high-speed LTE is more than adequate for all standard travel needs. In remote interior regions, networks may step down to 3G, which still handles messaging and basic browsing effectively.
Need to get work done from your eco-lodge or share data with a travel companion? Most French Guiana eSIM plans fully support personal hotspot (tethering), turning your phone into a secure Wi-Fi hub for your laptop or tablet.
Match your data allowance to your travel style to avoid running out or overpaying.
If you're in Kourou for a specific launch window or have a brief layover, a 1GB plan covers the essentials:
A 3GB to 5GB plan is ideal for a proper tour of the territory. This allows for daily use of maps, regular photo sharing from places like the Trésor Reserve, and some evening streaming. If you plan on using video calls frequently, opt for the 5GB option.
Digital nomads or those on month-long research trips should consider 10GB+ plans. This supports video conferences, large file transfers, and consistent navigation as you travel from the coast to the interior. Look for providers that offer easy top-ups if your project extends beyond the initial period.

For Android Users (Samsung/Pixel):
Smart habits ensure your connection lasts throughout your journey.
Your data will power crucial tools: translation apps for French and Creole menus, weather apps for sudden tropical downpours, and ride-hailing apps for getting around towns. WhatsApp is the primary communication method for contacting tour operators and lodges.
Your eSIM provides a more secure, private connection than vulnerable public Wi-Fi networks at airports or plazas. For online banking or accessing sensitive work documents, always use your mobile data connection for added peace of mind.
For anyone traveling to Kourou for a rocket launch, an eSIM is non-negotiable. Stream live broadcasts, get real-time schedule updates, and share the spectacle without buffering or excessive charges.
Exploring the Amazonian parks or the Marais de Kaw requires reliable data for GPS tracking, weather alerts, and emergency communication, even if just at the trailhead or lodge.
With French Guiana's role in aerospace and research, professionals need a steadfast connection for emails, video conferences, and accessing cloud-based work tools from anywhere on the coast.
How quickly does the eSIM activate after purchase?
You receive the QR code instantly via email. Activation occurs when you scan it and connect to a supported network in French Guiana.
Will my WhatsApp number still work?
Absolutely. WhatsApp uses your phone number for registration but operates over data. It will work seamlessly with your new eSIM connection.
Can I use my phone as a hotspot?
Yes, most plans allow personal hotspot/tethering, letting you share your data connection with other devices.
Is the eSIM for data only, or does it include a local number?
Most travel eSIMs are data-only, which is perfect for using WhatsApp, Skype, FaceTime, or other VoIP apps for calls and texts.
What if I use all my data before my trip ends?
You can usually purchase a top-up or a new data plan online, provided you still have some connectivity to do so.
Can I use the same eSIM in Brazil or Suriname?
Typically, plans are specific to French Guiana. Check for dedicated "South America" regional plans if you're visiting multiple countries.
How long is the eSIM valid?
Plans typically last 7, 15, or 30 days, with the countdown starting from your first connection to the local network.
How do I know if my phone is eSIM compatible?
Check your cellular settings for an "Add eSIM" or "Add Cellular Plan" option. Your device must also be unlocked from your home carrier.
Do I need to take out my physical SIM card?
No, you can use both simultaneously. Simply configure your phone to use the eSIM for data while keeping your physical SIM active for calls (if needed).
Which local networks provide the best coverage?
Our eSIMs connect to the strongest available networks, such as Orange or Digicel, ensuring reliable service in urban and key tourist areas.
An eSIM is the definitive solution for modern travel in this unique destination. It removes the friction of staying online, letting you focus entirely on the experience—whether that's marveling at a space launch, spotting a toucan in the rainforest, or savoring the local cuisine.
Gain the freedom to explore with confidence, knowing you have a reliable, affordable data connection in your pocket from the moment you arrive.
From the depths of the Amazon to the heights of the Guiana Space Centre, stay linked to the stars and the world.
