Caribbean: which Internet solution to choose when you change islands frequently? A guide to optimal connectivity
To travel from island to island in the Caribbean is to live an adventure of freedom, discovery and paradisiacal landscapes. But between two flights, a ferry or a change of accommodation, staying connected quickly becomes a headache. Which mobile package should you choose? What Internet connection should you choose to maintain a good network without blowing your data budget?
This comprehensive guide will help you choose the best Internet solution in the Caribbean, whether you’re a digital nomad, a professional on the move or just a curious traveler.
Internet connection options in the Caribbean
Mobile Internet: a flexible solution for travelers
Today, mobile Internet remains the most practical solution for travelers. International eSIMs
allow you to connect as soon as you arrive on site, without going through a local operator.
They offer several advantages:
- Instant activation from your phone
- Compatible with most recent smartphones
- Multi-island coverage in French overseas departments and territories (Guadeloupe, Martinique, Saint-Martin, etc.)
- No change of number or physical card to insert
Discover eSIM Caribbean, specially designed for travelers who change islands frequently.
If you’re staying on a single island for more than a month, a local SIM card may be cost-effective (Orange, SFR Caraïbes, Digicel). But for multi-island trips, eSIM remains unbeatable: it avoids losing the network or deactivating a SIM at each border.
Public and private wi-fi: advantages and disadvantages
Public Wi-Fi (airports, cafés, hotels) can help out, but it often remains :
- Slow or unstable,
- Limited bandwidth,
- Little security for your personal data.
For professional or intensive use, prefer a pocket Wi-Fi router. These small devices enable you to connect several phones or computers at the same time via a 4G connection. However, they cost more (purchase + data top-up) and coverage still depends on the local mobile network.
Satellite Internet: is it right for the Caribbean?
Internet via satellite (like Starlink) seduces with its promise of a network available everywhere, even at sea. But in reality :
- Costs remain high (over €100 per month),
- The equipment is bulky,
- Latency can be a problem for calls or videoconferences.
This solution is best suited to long-term residents or boats sailing between several islands. For a one-off trip, it’s better to opt for a prepaid eSIM or a flexible mobile package.

Tips for optimizing your Internet connection
- Disable automatic updates and HD streaming when using data.
