HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric overall, with App 5.0/5 and Support 5.0/5, and prices Caribbean destinations from $3.50/GB, the lowest fixed rate among the three full-coverage providers compared here, while its 204+ carrier partnerships route through the same FLOW and Digicel networks that dominate the English-speaking islands. Its 186-country reach also covers onward travel into Central or South America from a Caribbean base without a second eSIM purchase.
Dimension scores, 0-5 on our rubric
Pros
- 186 countries with 204+ carrier partnerships for reliable local routing
- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration
- iOS and Android app with in-app top-up, add-destination, and usage alerts
- Live chat, WhatsApp, and email support, including real-time channels
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Newer brand (launched August 2025) with shorter track record
- 186 countries, behind Airalo's 200+ catalogue
Airalo -- Widest Coverage Catalogue
Airalo lists nearly every Caribbean destination in this comparison, drawing on its 200+ country global footprint and an App score of 4.7/5 on our 2026 rubric, useful for tracking data usage across a multi-island itinerary. Its $4.50/GB headline rate sits above HelloRoam's $3.50/GB and Saily's $3.99/GB, the trade-off for the widest coverage list across these 27 island nations.
Dimension scores, 0-5 on our rubric
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Automatic in-app install with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- No live chat or WhatsApp channel: support runs on email and in-app messaging
Saily -- Best for Privacy
Saily's $3.99/GB rate undercuts Airalo's $4.50/GB across the Caribbean islands it covers, and its bundled VPN adds encryption value on the resort and cruise-port WiFi networks travelers rely on between eSIM data sessions. Its 200-country footprint still leaves gaps among the smaller Eastern Caribbean islands that HelloRoam and Airalo both list.
Dimension scores, 0-5 on our rubric
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost
- Clean, privacy-focused app with VPN toggle inside the eSIM interface
- 200 countries with strong European coverage
- 30-day refund policy
Cons
- Email-only support with no live chat or WhatsApp for urgent help
- Fixed data plans only; no unlimited daily tier
- 200 countries, just behind Airalo's 200-plus
Holafly -- Best Unlimited Daily Rate
Holafly's unlimited daily plans from $2.99/day score 4.5/5 on Pricing (Nomad leads Pricing at 4.8/5) for cruise-hoppers and long-stay travelers who cross several islands on one trip, where fixed-GB plans from competing providers can run out mid-itinerary. Its 160-country footprint covers the major Caribbean tourist routes, though HelloRoam and Airalo list more of the smaller island nations compared here.
Dimension scores, 0-5 on our rubric
Pros
- Unlimited daily data from $2.99/day with no data caps
- 160+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 180-day refund policy on unused plans
- 24/7 chat support alongside email
Cons
- Speeds reduce after the daily fair use threshold on most plans
- Hotspot tethering limited to 1 GB/day on select destinations
- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Nomad -- Best Budget Per-GB Rate
Nomad's discounted pricing tier concentrates in Southeast Asia, and its general $3.00/GB rate does not extend the same discount into Caribbean markets, where its 200-country footprint still leaves out several of the smaller islands that HelloRoam and Airalo both cover. Its Support score of 3.9 is also the lowest in this five-provider matrix, a relevant gap for travelers island-hopping where on-the-ground troubleshooting options are limited.
Dimension scores, 0-5 on our rubric
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
- Plans start at a low entry price for short trips
Cons
- Email-only support with no live chat, WhatsApp, or phone channel
- Basic app compared to Airalo and Saily
- 200 countries, behind only Airalo among the five providers
- Limited plan variety in some countries
