Benefit #1: Mobile Coverage Across Most of the Caribbean

A regional plan covers not just a single country, but the main Caribbean islands – including independent nations like Cuba, Jamaica, the Dominican Republic, and others, as well as overseas territories such as Martinique and the Cayman Islands. 3G-4G coverage is available across most populated areas:

• Dominican Republic: ~99% of the inhabited territories;
• Jamaica: ~99%;
• Barbados: ~99%.

Note: This refers specifically to populated areas such as major cities and along main highways, not the entire country. Due to underdeveloped infrastructure, the signal may be unavailable in remote villages, jungles, forests, and other similar locations.

For example, in Jamaica, your phone can access 5G only in major cities, while in the Dominican Republic, 5G is available across about 8% of the country. However, in Puerto Rico, 5G networks cover roughly 72.5% of the territory. Coverage varies by country, but even in Cuba, you’ll get 4G across approximately 50% of populated areas (5G is currently unavailable).

At PrimaSIM, we achieve such extensive coverage by partnering with multiple top local operators: Digicel (Jamaica, Barbados, Trinidad & Tobago), Claro (Dominican Republic), Flow, and Aliv.

Benefit #2: High-Speed Mobile Internet via eSIM in the Caribbean

The average download speed across the Caribbean is around 55 Mbps, though it varies significantly by country. However, thanks to the ability to connect to different local networks, you can get the maximum possible speed. For example, average speeds are:

• Dominican Republic: 57.4 Mbps;
• Barbados: 46.0 Mbps download, 7.6 Mbps upload;
• Puerto Rico: 118.54 Mbps;
• Cuba: 5.78 Mbps.

Also, in Puerto Rico, 5G offers an average speed of 193.3 Mbps. In many other countries, operators are still working on deploying 5G and increasing network speeds.

Benefit #3: One eSIM for Multiple Countries

You don’t need to buy a new plan when crossing borders – your internet access stays uninterrupted. This is the perfect solution if you’re planning a trip across several Caribbean islands. Plus, you can save by purchasing a single large package at the lowest price per GB (20 GB or 50 GB).
