travelplanet.cc eSIM & SIM Cards for the Caribbean – Comparison 2026
🌍 Overview – What You Need to Know ↑ Back
The Caribbean is not a single telecom zone. It consists of dozens of distinct islands and countries, each with its own mobile network operators. There is no single universal SIM card that covers all destinations . A local SIM from one island will not work on the next, making a regional eSIM the most convenient choice for island-hopping .
Key Facts at a Glance
- Local SIMs: Require a new one for each island, often need passport registration, and are only available on the island itself .
- EU Roaming: Works on French islands (Martinique, Guadeloupe) but not in the Dominican Republic, Jamaica, Bahamas, etc. .
- Regional eSIMs: The best option for multi-island trips. They connect to local networks like Digicel, Flow, Claro, and Orange automatically when you arrive on a new island .

💡 Practical Tips for Caribbean Travelers ↑ Back
- Install your eSIM before you go: Activating at home avoids airport Wi-Fi and saves time .
- Check your coverage: Not all eSIMs cover every Caribbean island. Check the coverage map .
- Hotspot limits: Holafly caps hotspot sharing at 500 MB/day .
- Beware of "unlimited": Many providers hide Fair Use Policy (FUP) limits – Holafly is one of the few with no throttling .
- Data needs: 1-3 GB per week is enough for maps, messaging, and light browsing. For streaming, choose unlimited.
- French islands: EU roaming works on Martinique and Guadeloupe .
- Cuba: Most eSIMs don't work in Cuba – get a local ETECSA SIM .
