eSIM Providers for Guadeloupe (2026) — 5 Compared

Provider scores for Guadeloupe come from five data-driven dimensions. Pricing Tiers (20%) and Coverage Breadth (20%) carry equal weight because cost and connectivity matter most to travelers. Network Generation (20%) uses the 5G technology Orange carries. App Features (20%) evaluates installation steps, APN auto-configuration, and in-app data tracking. Support Channels (20%) factors in refund policy length and which channels are real-time — Holafly runs 24/7 chat, Saily and Nomad are email-only. Scores update when carrier routing or pricing changes for Guadeloupe.

Airalo leads on coverage breadth for Guadeloupe with a 4.9/5 in our comparison matrix coverage score and 200+ country network footprint. Coverage routes through Orange. For Guadeloupe specifically, all five providers access the same 5G infrastructure, so urban coverage is comparable between them. Airalo's coverage advantage matters most for multi-country itineraries extending beyond Guadeloupe — 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 Guadeloupe; (2) Coverage — which local carriers each provider routes through and 5G 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 Guadeloupe.

Most travelers to Guadeloupe 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 $3.49/day. WiFi at hotels and cafes in Guadeloupe reduces cellular consumption by 30-60% depending on usage patterns.

Airalo supports in-app top-ups for Guadeloupe — purchase additional data without installing a new eSIM. Holafly's unlimited plan eliminates top-up need entirely. Saily requires a new eSIM purchase for more data. Nomad also requires a separate purchase. Top-ups need an internet connection: WiFi (moderate availability in Guadeloupe) or remaining cellular data. Buy top-ups before your current plan runs out to avoid being offline in Guadeloupe while trying to purchase more data.

Install your Guadeloupe eSIM 24-48 hours before departure while you have stable WiFi. Do not enable data roaming until you land. Most providers start the plan validity clock at first data use, not at installation. Airalo and Holafly both confirm this policy for Guadeloupe. Saily and Nomad start validity on first connection. Install early to troubleshoot any QR scanning issues while you still have home internet. Enable data roaming in Guadeloupe only after landing and clearing customs.

Set your travel eSIM as the data line and keep your home SIM for calls and texts. On iPhone: Settings > Cellular > select the Guadeloupe eSIM line > Turn On This Line > set as Cellular Data. On Android: Settings > Network > SIM Manager > set eSIM as mobile data. Disable Data Roaming on your home SIM to prevent charges. Enable Data Roaming on the Guadeloupe eSIM only. All five providers — HelloRoam, Airalo, Holafly, Saily, Nomad — work in dual SIM mode.

Guadeloupe travel eSIMs run on 5G. All five providers — HelloRoam, Airalo, Holafly, Saily, Nomad — access the same Orange 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 Guadeloupe depends on Orange's network infrastructure, not the eSIM provider. All five — HelloRoam, Airalo, Holafly, Saily, Nomad — deliver standard 5G 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 Guadeloupe. Network generation carries 20% of our composite score but rarely differentiates providers for any single country.

Airalo leads on multi-country support. Airalo offers regional bundles — Asialink (16 countries), Eurolink (39 countries), Discover Global (130 countries) — that cover Guadeloupe alongside neighboring countries on a single eSIM profile. Holafly also offers multi-country plans in Caribbean. Saily and Nomad require a separate eSIM per country, which adds switching friction for complex itineraries. If Guadeloupe is your only stop, any provider works and the decision comes down to pricing and refund policy.

Guadeloupe eSIM prices range from $1.03 for 1GB (entry level) to $14.19 for 20GB (largest fixed plan). Unlimited daily data is available from $3.49/day. The lowest per-GB rate is $0.64 on the highest-volume fixed tier. All five providers — HelloRoam, Airalo, Holafly, Saily, Nomad — offer Guadeloupe plans with pricing set by their individual margin structures on the same Orange carrier infrastructure.

You can switch providers during your Guadeloupe 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.

Travel eSIMs for Guadeloupe are tied to the device they are installed on. Airalo is the most flexible — unactivated profiles can be reinstalled on a new phone. Holafly, Saily, and Nomad issue single-use QR codes. If you need to switch phones after installation, contact the provider's support team before attempting to activate in Guadeloupe. Apple's built-in eSIM Transfer feature handles carrier eSIMs only, not travel eSIMs. Plan your device choice before purchasing.

Rural Guadeloupe coverage depends on Orange's infrastructure, not your eSIM provider. 5G towers cover cities and tourist corridors. Rural areas fall back to 3G. HelloRoam, Airalo, Holafly, Saily, and Nomad all access the same 1 carrier in Guadeloupe — no provider has a rural advantage. For off-grid travel: download offline maps, save key addresses, and use WiFi at accommodations for data-heavy tasks. A fixed 3-5GB plan handles rural travel (less streaming, more maps).
