eSIM Travel Tips for French Guiana
Install your eSIM before departure
Set up your HelloRoam eSIM at home before flying to French Guiana. Enable mobile data at Cayenne Airport and you are online immediately. No carrier store search needed.
Download offline maps for the Amazon
The Amazonian interior of French Guiana has no mobile coverage. Download offline maps for any jungle trips, national park visits, or Maroni River journeys before leaving Cayenne.
French Guiana uses EU pricing
French Guiana is an overseas department of France, so it uses the euro and some EU regulations apply. However, mobile roaming rules differ here from mainland France, which is why separate eSIM pricing applies.
Track your data balance
The HelloRoam app tracks your data in real time with alerts at 80% and 95%. Top up from the app if needed without reinstalling your eSIM profile.
Save emergency contacts
French Guiana uses the French emergency number 15 for medical (SAMU), 17 for police, and 18 for fire. The European 112 also works. Save these before you travel.

Best Time to Visit French Guiana
French Guiana has two dry seasons: mid-August to mid-November and February to mid-March. The long rainy season (April to July) can make jungle trails and river routes difficult. The Kourou space rocket launches (ESA) happen throughout the year. Network coverage on the coastal strip is consistent year-round. Offline maps are essential for any journey into the Amazonian interior.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer

Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
