Holafly -- Best Unlimited Data
Holafly's $2.99/day unlimited rate carries the same 2GB daily volume threshold tracked for Grenada before its fair-use throttle applies, and its 4.8/5 Pricing score leads the matrix. Grenada's own unlimited tier runs a full 30 days at $14.76 per day, so Holafly's flat rate still beats the country's longest tracked unlimited option.
Pros
- Unlimited daily data from $2.99/day with no data caps
- 178+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 6-month refund policy on unused plans
- 24/7 chat support with fast response times
Cons
- Speeds reduce to 256 Kbps-1 Mbps after 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
Airalo -- Best Overall Coverage
Airalo's $4.50/GB starting rate sits below Grenada's own $7.47/GB tracked floor, backed by the highest Coverage score in the matrix at 4.9/5 across 200+ countries. Its Discover Global bundle, spanning up to 130 countries on one eSIM, suits travelers pairing Grenada with a wider Caribbean island-hopping itinerary.
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Highest-rated app (4.8/5 iOS, 4.6/5 Android) 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
- Customer support slower than premium providers (4-6 hour email response)
HelloRoam -- Best Coverage + Value
HelloRoam scores 8.6/10 overall and prices Grenada from $3.50/GB, well under the country's own $7.47/GB tracked floor set by its cheapest 10GB tier. Its 204+ carrier partnerships and 63-language checkout give it real footing in a market where FLOW and Digicel both operate documented local coverage.
Pros

Saily -- Best for Privacy
Saily prices Grenada at $3.99/GB with a bundled NordVPN connection at no extra cost, useful since VPN access stays unrestricted per enrichment data. Its 150-country footprint and 4.6/5 App score still beat Grenada's own $7.47/GB comparison floor by a comfortable margin.

Nomad -- Best Budget Option
Nomad's $3.00/GB rate is the lowest fixed floor across all five providers, well under Grenada's own $7.47/GB tracked rate. Its 112-country footprint is the narrowest of the five, worth weighing against a Caribbean island where FLOW and Digicel already provide good documented main-island coverage.
Pros

- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
