Data plans for French Guiana without roaming fees
Every plan is data-only and prepaid. You select your data allowance and validity period before you travel, then receive a QR code by email. There is no physical SIM card, no contract, and no surprise roaming charges. Plans start with 500 MB valid for 1 day and scale up depending on how much data you need and how long you are staying.
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 4G/LTE or 5G where the underlying network and your device support it.
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 4G connectivity. 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.
If you are traveling beyond coastal towns, download offline maps and any information you need before you leave connected areas. A 500 MB or 1 GB plan is usually enough for a short stay focused on Cayenne and day trips. If you are spending a week exploring multiple towns, attending a launch event, or streaming content, consider a larger data allowance. French Guiana uses the euro and most establishments accept cards, but mobile data is still helpful for confirming transport schedules and staying in touch with tour operators.
Frequently asked questions
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.
