Orange network coverage in Saint Barthelemy
Orange carries all 6 of HelloRoam's Saint Barthelemy plans and is the only network on the island, so coverage and plan choice are one question here. It operates under French overseas collectivity telecommunications rules. The island's small size, approximately 25 km across, means a single carrier covers the entire surface with 4G LTE.
Orange covers Gustavia harbor, all major beaches including Saline, Flamands, St Jean, Grand Cul-de-Sac, and the residential hilltop areas. There is no significant dead zone on the island.
通信範囲の分析
Orange covers all of Saint Barthelemy's inhabited areas. Gustavia's harbourfront, the Nikki Beach area at St Jean, and the Saline and Gouverneur beaches all have strong 4G. The hilltop roads and villa areas above Gustavia maintain reliable signal.
The uninhabited northern tip near Pointe Milou has good coverage from the island's elevation. Sea-level coverage extends approximately 1-2 km offshore, covering most water sports and yacht anchorage areas.
開通方法
Install your eSIM QR code before flying into Gustaf III Airport (SBH). Orange activates automatically on arrival. No airport SIM shop exists on the island, so pre-installing is essential for immediate connectivity.
Enable data roaming in your settings upon landing. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer support eSIM. Your device must be carrier-unlocked.
データ通信の活用のコツ
St Barts visitors typically use 300-500 MB per day for restaurant reservations via OpenTable, Google Maps for beach navigation, and WhatsApp with villa staff. Sharing yacht photos and beach content on Instagram adds 200-400 MB per session. The 2 GB day pass at $5.99 suits villa guests without included Wi-Fi.
Property management apps and concierge services on the island work via WhatsApp, using minimal data. Streaming music from beaches adds roughly 50-100 MB per hour.
Saint BarthelemyのeSIMプラン料金
Saint Barthelemy prices as a small-island market running on French infrastructure. The 1 GB plan costs $5.70 over 7 days, and 3 GB costs $16.10 over 30 days. The 5 GB plan costs $23.99, and the 10 GB plan at $34.99 lands at $3.50 per GB.
The 20 GB plan at $43.99 improves that to $2.20 per GB. A single villa day runs on the 2 GB day pass at $5.99. Speed drops under fair-use terms once that daily allowance is spent.
Verdict: HelloRoam sells 6 Saint Barthelemy plans on Orange 5G from $5.70 for 1 GB, and its 20 GB plan at $43.99 gives $2.20 per GB.
