eSIM Providers for Grenada (2026) — 5 Compared

We score each provider on five weighted dimensions for Grenada: Pricing Tiers (20%) — per-GB cost and plan range; Coverage Breadth (20%) — carrier routing quality and 4G LTE network reach via FLOW; Network Generation (20%) — which technologies the local network carries; App Features (20%) — installation flow and eSIM management; Support Channels (20%) — which channels exist and how long the refund window runs. HelloRoam, Airalo, Holafly, Saily, and Nomad are scored independently for each destination. The same provider can rank differently for Grenada versus other countries depending on local carrier partnerships and pricing.

Airalo leads on coverage breadth for Grenada with a 4.9/5 on our 2026 rubric coverage score and 200+ country network footprint. Coverage routes through FLOW. For Grenada specifically, all five providers access the same 4G LTE infrastructure, so urban coverage is comparable between them. Airalo's coverage advantage matters most for multi-country itineraries extending beyond Grenada — Holafly, Saily, and Nomad score equally for single-country trips.

The comparison matrix evaluates five dimensions: (1) Pricing — entry price, per-GB rate at each tier, and whether unlimited daily is available for Grenada; (2) Coverage — which local carriers each provider routes through and 4G LTE network quality; (3) Network — which generations the local carriers run, and where each is available; (4) App quality — eSIM installation flow and APN auto-configuration; (5) Refund policy — Holafly offers 180 days, Saily and Nomad 30 days, Airalo 14 days. All five scores combine into the overall ranking for Grenada.

Most travelers to Grenada use 1-2GB per day on cellular. Maps, messaging, and social media consume 500MB-1GB daily. Streaming video pushes usage to 3-5GB per day. For a 7-day trip with moderate WiFi availability, a 5GB fixed plan covers light-to-moderate usage comfortably. Heavy users should consider Holafly's unlimited daily plan at $18.00/day. WiFi at hotels and cafes in Grenada reduces cellular consumption by 30-60% depending on usage patterns.

Unlimited data in Grenada costs $18.00/day through Holafly — $126.00 for a 7-day trip. A 5GB fixed plan costs $40.80. The breakeven point: if you use more than 6GB during your Grenada trip, unlimited becomes cheaper per-GB. Remote workers streaming video or on daily video calls easily exceed 5GB per day, making unlimited the clear value play. Casual travelers using maps and messaging rarely need unlimited.

Install 24-48 hours before your Grenada flight. Keep data roaming off until you land. Plan validity for all five providers starts at first data usage — installing early does not waste days. The install-before-departure rule exists because QR scanning needs a stable internet connection (WiFi or current cellular). If something goes wrong with the scan, you can contact support before boarding. Once in Grenada, enable data roaming in Settings and the eSIM connects to FLOW within 60 seconds.

Dual SIM configuration for Grenada: install the travel eSIM, then go to Cellular/SIM settings. Set the eSIM as "Mobile Data." Set your home SIM as "Default Voice." Disable Data Roaming on the home SIM — this prevents carrier roaming charges. Enable Data Roaming on the Grenada eSIM to connect on arrival. iPhone supports this natively from iPhone XS onward. Samsung, Google Pixel, and OnePlus support it on most recent models. All five eSIM providers (HelloRoam, Airalo, Holafly, Saily, Nomad) function alongside a physical SIM.

Grenada travel eSIMs run on 4G LTE. All five providers — HelloRoam, Airalo, Holafly, Saily, Nomad — access the same FLOW infrastructure, so the network is the same whichever one you buy. Peak-hour slowdowns affect all providers equally in dense urban areas. We publish no speed measurements, because we do not measure anyone's network.

Speed in Grenada depends on FLOW's network infrastructure, not the eSIM provider. All five — HelloRoam, Airalo, Holafly, Saily, Nomad — deliver standard 4G LTE service because they share the same towers. Think of it like five airlines boarding the same plane: the flight speed is identical regardless of which ticket you bought. Peak congestion and rural coverage gaps affect all providers equally in Grenada. Network generation carries 20% of our composite score but rarely differentiates providers for any single country.

For Grenada, the five providers split into clear use cases. Airalo scores highest for multi-country itineraries — 200+ destinations on a single account. Holafly scores highest on unlimited daily data if you stream or work remotely. Saily scores highest on privacy with built-in VPN protection (NordVPN infrastructure) at no extra cost. Nomad has the lowest per-GB price if cost is the deciding factor, starting from $10.98 for 1GB. Fixed data plans suit trips under 14 days; unlimited daily makes sense when you burn 5+ GB per day.

eSIM transfer between devices depends on the provider, not the country. Airalo supports re-downloading an unactivated eSIM profile on a new device. Holafly, Saily, and Nomad generally allow one installation per purchase — contact support before activating on the new device. Apple's eSIM Transfer feature (iPhone-to-iPhone via cable or iCloud) does not apply to third-party travel eSIMs. Always install your Grenada eSIM before factory-resetting or trading in your phone.

Refund policies differ across the five providers for Grenada plans. Holafly offers the most generous policy: 180 days to request a refund on unused plans. Saily and Nomad both offer 30-day refund windows for unused eSIM profiles. Airalo provides a 14-day refund period. All five require the plan to be unused — no data consumed — to qualify. If you have already activated and used data in Grenada, refunds are at provider discretion.

Yes — all five providers support hotspot for Grenada eSIMs. Turn on Personal Hotspot (iPhone) or Mobile Hotspot (Android) and connected devices share your 4G LTE data. The tradeoff: hotspot multiplies consumption 3-5x. A 10GB plan with continuous hotspot use lasts 3-4 days instead of 10+. Holafly's unlimited plan is the safest choice for hotspot-heavy travel in Grenada. Airalo, Saily, and Nomad fixed plans work for occasional tethering but drain fast under sustained use.

You can switch providers during your Grenada trip by purchasing and installing a new eSIM. WiFi is required to download the new profile. iPhone 13+ supports multiple eSIM profiles — install the new one alongside the old. Older iPhones need to delete the current eSIM first. Android varies by manufacturer. Refund windows: Holafly 180 days, Saily 30 days, Nomad 30 days, Airalo 14 days — unused data on the old plan may qualify for a refund. Switching takes 5-10 minutes on WiFi.
