Tips for Travelers in Saint Barthélemy
Make the most of your St. Barths trip with these connectivity tips from fellow travelers:
Download and install your AloOui Saint Barthélemy eSIM profile at home before departure. It won't activate until you land — so you're ready the moment you touch down at Gustaf III Airport.
Your AloOui eSIM runs alongside your existing SIM. Keep your home number for calls and WhatsApp while using the Saint Barthélemy eSIM for data — no need to choose.
Before heading to remote beaches like Colombier or Gouverneur — only accessible by boat or hiking trail — download offline maps on Google Maps or Maps.me. Even with unlimited data, offline maps save battery and load instantly in areas with weaker signal.
On the Unlimited Lite plan, enable Low Data Mode on your phone to stretch your 1GB daily full-speed quota further — great for beach days with light usage.
St. Barths' top dining experiences and water sports — from Nikki Beach to catamaran charters — book out fast, especially in peak season. Use your AloOui data to reserve online the moment you arrive.
Whether you're island-hopping to Saint Martin, exploring Gustavia's harbour, or relaxing at a hillside villa, your AloOui eSIM keeps you connected without relying on hotel or restaurant Wi-Fi.
For Business Travelers & Luxury Visitors
Saint Barthélemy is a premier destination for high-net-worth travelers, yacht owners, and business executives. Here's why AloOui's Unlimited Plus is the go-to plan for professionals visiting St. Barths.
The Plus plan gives you network priority — so even in busy Gustavia harbour during peak season, your connection stays fast and stable.
Video calls, large file uploads, cloud syncing — 2GB of full-speed data per day keeps your workflow uninterrupted, with 2 Mbps fallback for lighter tasks.
Share your connection with your laptop or tablet. Perfect for working from a Gustavia café or a luxury villa without relying on public Wi-Fi.
Extended stays covered. Whether you're on a month-long yacht charter or a long luxury retreat, one plan keeps you connected the whole time.
Scan a QR code and you're online. No SIM procurement, no corporate roaming plans, no waiting at a carrier store. Instant activation means you're productive from day one.
One flat rate, no surprise roaming bills. Ideal for expense reporting and budget-conscious professionals who need reliable data without unpredictable carrier charges.
