Data plans for French Guiana without roaming fees
esimbloom lists 13 prepaid eSIM plans for French Guiana from $0.77 (the smallest is 500MB for 1 day). Every plan is data-only — mobile internet for maps, messaging and bookings, but no local phone number or SMS — and prepaid: pay once, no contract, no roaming charges.
You will have mobile data for maps, messaging apps, and ride-hailing from the moment you scan the QR code. The plans do not include a local phone number, SMS, or voice calls. Internet calling through apps like WhatsApp and FaceTime works normally. Your connection runs on the local mobile network at whatever speed it and your device support.
How to install and activate your French Guiana eSIM
Check that your phone is unlocked and eSIM-compatible before you purchase. Most iPhones from XS onward and recent Android flagships support eSIM. After you complete your order, the QR code arrives by email within minutes. You can install the eSIM before you leave home by scanning the code in your phone's settings, but do not enable the data plan yet.
Turn on the eSIM data line after you arrive in French Guiana. Your device will connect to the local network automatically. If you installed the profile while still at home, make sure your primary SIM's data roaming is turned off so your phone uses the eSIM data. Activation is immediate and your validity period starts the moment you connect.
Staying connected in Cayenne and across French Guiana
Mobile coverage in French Guiana is concentrated along the coast. Cayenne, Kourou, and Saint-Laurent-du-Maroni have reliable coverage. Data works well for navigation around the capital, booking river transfers to the Îles du Salut, or checking launch schedules if you are visiting the European Space Agency facility. Coverage thins quickly as you move inland toward the Amazon rainforest. The interior and many nature reserves have limited or no signal.
Frequently asked questions
How much does an eSIM for French Guiana cost?
esimbloom French Guiana eSIM plans start at $0.77, with 13 plans to choose from. You pay once for the plan you pick — no roaming fees and no contract.
Do I need an eSIM for French Guiana?
Only if you want mobile data without roaming charges. An esimbloom French Guiana eSIM is installed from a QR code before you fly, activates on your first connection in French Guiana, and is data-only — your home SIM stays in the second slot for calls and SMS, with its data roaming switched off.
Do I need a separate eSIM for France and French Guiana?
Yes. French Guiana is an overseas department of France but uses a different mobile network infrastructure. European roaming agreements do not always extend here. Buy a plan specifically for French Guiana to avoid roaming fees or connectivity issues.
Can I use the eSIM in the rainforest or on the Maroni River?
Coverage is limited to coastal areas and main towns. Expect no signal in the interior rainforest, along most of the Maroni River beyond Saint-Laurent, and in remote nature reserves. Download maps and travel information before leaving connected zones.
Will the eSIM work at the Guiana Space Centre in Kourou?
Yes. Kourou has mobile coverage and your eSIM will work in the town and surrounding area. However, parts of the space centre complex may restrict mobile devices for security reasons during launch events or facility tours.
How much data do I need for a week in French Guiana?
For maps, messaging, and light browsing, 1–3 GB is typically sufficient for a week. If you plan to upload photos, stream video, or work remotely, consider 5 GB or more depending on your usage habits.
When does my plan validity start?
Your validity period begins the moment your device connects to the network in French Guiana. You can install the eSIM profile before you travel, but do not turn on the data line until you arrive to avoid wasting days of validity.
