eSIM for Guadeloupe

You'll move between Grande-Terre's beaches and Basse-Terre's rainforest often, and a steady connection keeps ferry times, trail notes, and WhatsApp plans within reach. Ride apps like Uber and Bolt haven't taken hold, so you'll book taxis directly or pick up a rental in Pointe-a-Pitre. Download offline maps before the drive to La Soufriere or Les Saintes, and keep a translation app ready for the French and Creole you'll hear in the markets.

How to install your Guadeloupe eSIM in 3 steps

Setting up your eSIM before you fly means you skip the search for a SIM counter at Pointe-à-Pitre airport and land already reachable across both Grande-Terre and Basse-Terre.

1. Pick a data allowance that matches your trip - anything from a 1GB pass for a short stopover to a 20GB, 30-day plan if you're island-hopping out to Les Saintes or Marie-Galante - and check out online before you leave home. Plans start from £0.97, with the cheapest 1GB option at £0.97.
2. Once your QR code arrives by email, open your phone's cellular settings, add a new plan, and scan it over Wi-Fi. Most eSIM-ready phones handle this in a couple of minutes, but confirm compatibility first - Guadeloupe's networks run on GSM, not CDMA, so older or region-locked handsets may not work.
3. Land in Guadeloupe, turn on data roaming for your new eSIM line, and your phone should pick up an Orange Caraïbe, Digicel, SFR Caraïbe or Free Caraïbe signal within a few minutes of touching down at Pointe-à-Pitre.

Coverage in Guadeloupe

Four operators share the archipelago - Orange Caraïbe, Digicel, SFR Caraïbe and Free Caraïbe - together reaching the large majority of the population with 4G across the main areas of Grande-Terre and Basse-Terre. Orange Caraïbe has the broadest rural reach and is generally the strongest choice on the outer islands, including Marie-Galante, Les Saintes and La Désirade.

5G is live in the urban core around Pointe-à-Pitre, Les Abymes and Le Gosier, but it remains largely an urban and suburban service. Outside that zone, 4G and 4G+ carry the connection - including through the coastal resort areas of Saint-François and Sainte-Anne, where 4G+ is consistently available.

Coverage thins out once you leave the main roads. Basse-Terre's mountainous interior - the Route de la Traversée, La Soufrière, and the national park's hiking trails - has dead zones and intermittent signal, so don't count on a steady connection mid-hike. The outer islands hold 4G in their main villages, such as Terre-de-Haut's harbour and Marie-Galante's towns, but coverage weakens further inland. Even on the mainland, the remote eastern tip at Pointe des Châteaux tends to flicker between 4G and 3G rather than holding a stable signal.

How much data do you actually need?

Guadeloupe's real eSIM plans run from 1GB to 20GB, valid for anywhere from 1 to 30 days. Here's roughly how usage maps to plan size:

Usage type	Typical daily use	Suggested plan
Light - maps, messaging, occasional browsing	Around 300 MB/day	1GB plan (7 days) - fine for a short stay around Pointe-à-Pitre or a day trip to Les Saintes
Moderate - social media, navigation, some streaming	Around 750 MB/day	3GB (30 days) or 10GB (30 days) - comfortable for a week or two touring Grande-Terre and Basse-Terre
Heavy - video calls, streaming, hotspot use	1.5GB/day or more	20GB (30 days) - suited to longer stays or trips that include ferry hops to Marie-Galante and Les Saintes

eSIM vs. roaming vs. a local SIM in Guadeloupe

All three routes will get you connected, but the trade-offs differ once you factor in Guadeloupe's rules and its status as an EU outermost region.

	eSIM	Home carrier roaming	Local physical SIM
Setup	Install the QR code before you fly, connect on arrival	Works automatically, no setup needed	Requires a shop visit, plus your passport for the (free) registration process
Cost	Fixed price paid upfront, from £0.97	EU/EEA numbers typically roam at home rates; non-EU travellers can face charges of around £7 to £11 a day, or over £1 per MB on pay-per-use	Prepaid local rates, but with the extra step of buying and registering it in person
Device requirements	Needs an unlocked, eSIM-capable phone	Works with whatever phone is already on your home plan	Phone must be GSM-compatible and unlocked - CDMA handsets aren't supported
Best for	Visitors who want data working the moment they land	EU/EEA travellers already covered by roam-like-home rules	Longer stays where you're settling into island life rather than passing through

Practical connectivity tips for Guadeloupe

Guadeloupe's ferry network links Grande-Terre to Les Saintes, Marie-Galante and the other outer islands, and crossings ranging from about 20 minutes to an hour and a half create real gaps in coverage - download maps, tickets and anything else you need before you board. If you're heading into Basse-Terre's interior, whether that's the Route de la Traversée, La Soufrière, or the national park trails, save your route offline too, since signal drops out in the mountains regardless of carrier.

Keep your passport handy if you'd rather register a local SIM - it's required for the free registration process, and only unlocked, GSM handsets are supported. Travelling on an EU/EEA number, your home carrier's roam-like-home rules should cover you here since Guadeloupe is an EU outermost region, though some carriers apply fair-use limits on remote territories, so it's worth checking the small print. Non-EU visitors should expect roaming charges to add up fast and may prefer to sort data out before arrival.

It's also worth saving Guadeloupe's emergency numbers before you land: 17 for police, 15 for ambulance/SAMU, 18 for fire, and 196 for distress at sea.
