HelloRoam runs French Guiana on Orange
HelloRoam routes French Guiana onto Orange, which is why all 6 plans hold the coastal strip where 95% of the population lives: Cayenne, Kourou, and Saint-Laurent-du-Maroni all sit inside Orange's footprint. Digicel operates mainly in the Caribbean islands and has little presence here. No other network offers eSIM-compatible service to international visitors in French Guiana, so Orange is the single route in.
通信範囲の分析
Orange covers the N1 coastal highway from Saint-Laurent-du-Maroni to Saint-Georges-de-l'Oyapock. Cayenne Félix Eboué Airport connects on arrival. The Guiana Space Centre in Kourou holds full coverage across the visitor areas.
Inland waterways toward the Amazonian interior lose signal within 30-50 km of the coast. The territory is 90% rainforest with no mobile infrastructure. Travelers taking river tours into the Amazon should treat connectivity as unavailable once away from the coast.
開通方法
Install your eSIM QR code before flying into Cayenne Félix Eboué Airport (CAY), and Orange registers the line after you land with no counter queue. French Guiana uses the +594 country code and sits in the UTC-3 time zone. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer support eSIM, and the device must be carrier-unlocked. European visitors on French Orange contracts sometimes find French Guiana already included as an overseas territory.
データ通信の活用のコツ
Budget 350-450 MB per day for maps, messaging, and travel logistics in Cayenne and Kourou. Download offline maps for the coastal areas, because the interior Amazon region has zero connectivity. Space Centre visitor programs run as guided tours, so check the Arianespace site on Wi-Fi before your visit.
The 3 GB plan at $6.48 covers a typical week across Cayenne, Kourou, and the coastal mangroves. Do not rely on data for navigation once you head inland.
French GuianaのeSIMプラン料金
French Guiana pricing sits mid-range for South America. Entry level: 1 GB / 7 days costs $3.49. The 3 GB plan costs $6.48 and the 5 GB plan costs $13.49.
The 10 GB plan runs $22.49 and the 20 GB plan runs $35.99, which works out at $1.80/GB. A daily plan costs $9.18 and carries a 2 GB allowance per day. Verdict: HelloRoam covers French Guiana at $13.49 for 5 GB on Orange, no rival in this comparison publishes a French Guiana price, and every plan is data only with no voice or SMS.
