Airalo (9.3/10) has the widest coverage across the Caribbean, covering 15+ islands from a single account. It routes through Digicel and Flow on 4G LTE networks across the region. The 3 GB plan suits a standard 5-day island stay. Cruise travelers save 80% on port-day connectivity versus cruise line WiFi packages. For unlimited data at resorts, Holafly starts at $2.99/day.
Island coverage is the core decision for Caribbean travel. Airalo covers 15+ Caribbean islands while Nomad covers 8 and Saily covers 6. For island-hopping trips or cruises that visit multiple ports, Airalo is the only practical choice.
Airalo routes through Digicel and Flow, the two carriers that dominate Caribbean mobile infrastructure. Digicel operates in Jamaica, Barbados, Trinidad and Tobago, and 10 other Caribbean markets. Flow covers the Bahamas, Antigua, Saint Lucia, and other eastern Caribbean islands. Together, these two carriers give Airalo strong 4G LTE coverage across the region.
Airalo scored 5.0 out of 5 on coverage and 4.9 out of 5 on app quality in our testing. The real-time data tracking in the Airalo app helps cruise travelers monitor usage across multiple port stops without unexpected data shortfalls. The app’s direct installation feature cuts setup time to under two minutes on supported iPhone and Android devices.
Cruise travelers gain the most from Airalo’s Caribbean coverage. One account handles every port on a 7-day Caribbean itinerary without buying local SIMs at each dock. Enable data when docked and enable airplane mode when heading back to sea. A 1 GB plan per port day at $4 to $6 each covers typical shore excursion usage including navigation, restaurant searches, and social media.

For a 5-day single island trip, a 3 GB plan covers moderate usage at 0.6 GB per day. A 10-day island-hopping trip needs 8 to 10 GB. Caribbean data usage tends to be lower than in busy cities because beach and outdoor activities reduce screen time. Airalo’s Americas regional bundle covers multiple Caribbean and Latin American countries on one plan, which suits complex itineraries that combine Caribbean islands with Costa Rica, Colombia, or Mexico.
Cruise passengers spend 8 to 12 hours at each port. An eSIM activated at port gives full 4G coverage for shore excursions, navigation, ride-hailing, and restaurant research. The strategy is straightforward:
Install your eSIM QR code over ship WiFi before your first port stop. On embarkation day, scan the QR code and complete installation using the ship’s WiFi before you need cellular data. When the ship docks at the first port, disable airplane mode. The eSIM activates automatically on the local carrier. When you return to the ship, enable airplane mode to avoid accidentally connecting to the ship’s maritime cellular network, which charges extreme roaming rates of $2 to $5 per MB.
A 7-day Caribbean cruise with 4 port days costs $16 to $24 on Airalo eSIM ($4 to $6 per port day for 1 GB). The same cruise ship WiFi package runs $89 to $154 depending on the cruise line. Carnival Surf WiFi costs $89 for 7 days. Royal Caribbean Surf costs $112 for 7 days. Norwegian Premium costs $105 for 7 days.
The recommended approach: buy the cheapest cruise ship WiFi tier for at-sea days when cellular is unavailable, and use eSIM at every port. The cheapest cruise WiFi packages cost $45 to $60 for 7 days. Add Airalo eSIM at $16 to $24 for port days. Total: $61 to $84. That is 38 to 45% cheaper than buying the premium cruise WiFi package alone, and you get faster speeds at ports.

Caribbean hurricane season runs from June through November. Network outages are possible during and after major storms. Pre-download offline maps, hotel confirmation PDFs, and emergency contacts before each port stop. Do not rely on live navigation during storm warnings. Unlimited plans from Holafly provide a buffer against congestion as networks recover after weather events.
Holafly scores 8.9/10 and covers the Dominican Republic, Jamaica, Puerto Rico, and Bahamas with unlimited daily data at $2.99 per day. For all-inclusive resort stays where streaming by the pool, posting beach photos, and video calling home are daily habits, unlimited removes data tracking entirely.
Holafly’s weakness for the Caribbean is coverage gaps. It misses smaller eastern Caribbean islands including Dominica, Grenada, Saint Vincent, and some French Antilles. For island-hopping trips that include these destinations, Holafly requires supplementing with Airalo for specific islands.
Choose Holafly for single-island resort stays in Jamaica, Dominican Republic, or Puerto Rico where daily usage exceeds 3 GB. The break-even point versus Airalo fixed data sits at 3.5 GB per day. Below that threshold, Airalo costs less. Above it, Holafly unlimited saves on overage risk and top-up purchases.
Caribbean resort WiFi typically slows to 2 to 5 Mbps at peak pool hours. Holafly on Digicel’s 4G network delivers 15 to 25 Mbps in the same location, which is 3 to 12 times faster. Most resort premium WiFi plans charge $10 to $20 per day. Holafly at $2.99 per day delivers better speed at 70 to 85% less cost.

Nomad covers 8 Caribbean islands including Jamaica and Dominican Republic at competitive per-GB rates. Jamaica runs around $3.00 per GB through Nomad. Dominican Republic runs around $3.20 per GB. For single-island budget trips to the two most popular Caribbean destinations, Nomad saves roughly 25 to 33% versus Airalo.
Nomad’s 8-island Caribbean coverage works for straightforward resort trips. It does not work for cruise port-day strategies covering 4 or more stops, since it misses most islands outside the two largest markets. For any island-hopping or cruise itinerary, switch to Airalo for the coverage breadth.
