Seen from above, Guadeloupe looks like a butterfly: the beaches and resorts of Grande-Terre on one wing, the rainforest, waterfalls and La Soufrière volcano of Basse-Terre on the other, with Les Saintes, Marie-Galante and La Désirade a short ferry ride away. This overseas region of France belongs to the EU, so Roam Like at Home applies and EU SIMs behave just as they do in their home country. The archipelago is, however, outside the Schengen area, and anyone arriving with a SIM from outside the EU pays that operator's roaming charges.
Key facts for Guadeloupe
- EU roaming: covered by Roam Like at Home
- Local networks: Digicel (depending on the plan)
- Emergency numbers: 112; ambulance 15; police 17; fire 18; distress at sea 196
- Embassies: none on French territory; British consular help comes from Paris, US help from Barbados
La Soufrière and the rainforest
La Soufrière, the highest point of the Lesser Antilles, is an active volcano under constant watch; in July 2026 its alert level remained yellow, meaning vigilance, with hot gases and carbon dioxide escaping from small vents along one of its trails. The summit has a no-entry zone and a restricted zone, so keep to the paths that are open and read the signs at the trailhead. Download offline maps before setting out on the trails of Basse-Terre's national park.
Beaches, sea and seaweed
Most visits pass without trouble, but avoid isolated areas, including beaches, after dark, and do not carry large amounts of cash or flashy jewellery. Be wary of beach sellers and of unfamiliar boats that approach you. Dive schools vary, and some have limited resources and do not always follow safety standards, so choose an established centre. When sargassum seaweed washes up and rots, it releases hydrogen sulphide gas, which smells of rotten eggs; keep away from heavy strandings and follow local notices.
Hurricanes, rain and health
The hurricane season runs from June to November, peaking in September, and the wet season from May to November brings flash floods. Leptospirosis is endemic and rises in the rainy months, so avoid fresh water if you have cuts, and use repellent against the mosquitoes that carry dengue and Zika. Healthcare matches the standard of mainland France, and European health insurance cards, like the UK's GHIC, cover medically necessary treatment in the public system.
Getting around
Public transport is infrequent outside the main towns, so renting a car is recommended. Ferries run from Grande-Terre and Basse-Terre to Les Saintes, Marie-Galante and La Désirade, and the Express des Îles links Guadeloupe with Martinique, Dominica and Saint Lucia; on board, your phone may pick up the networks of neighbouring islands, so check your data settings before you sail. French driving rules apply.
Entry and money
As one of the EU's outermost regions, Guadeloupe applies EU law but not the Schengen rules. An identity card is enough for EU citizens, British visitors can stay for up to 90 days without a visa, and a Schengen visa on its own will not get you in. Money is the euro; ATMs are common and larger shops take cards.
Getting connected
With an EU SIM: nothing changes; you use the local networks exactly as you would at home.
From outside the EU: add a travel eSIM before you leave so that it connects as you land at Pointe-à-Pitre. A Caribbean plan also works in Martinique, Dominica and Saint Lucia, which is handy on the ferries. Leave your own SIM active for bank messages, but with its data roaming off.
Local SIMs: Digicel, Orange and Outremer Télécom are among the operators; Digicel asks for an official ID document to sell a prepaid SIM.
Consular protection: who to call in Guadeloupe
- The emergency services answer on 112, or on 15 (ambulance), 17 (police) and 18 (fire); at sea, dial 196.
- Guadeloupe is French territory, so there are no embassies: British nationals are helped by their embassy in Paris and Americans by theirs in Bridgetown, Barbados. Find out before you go where your own country's consular help comes from.
- French is the official language, and most people also speak Guadeloupean Creole.
Questions travellers ask about Guadeloupe
Will my EU SIM work in Guadeloupe?
Yes, exactly as at home: the island is in the EU and Roam Like at Home applies.
Can I climb La Soufrière?
Yes, on the trails that are open: the summit has no-entry and restricted zones because of volcanic gases, so follow the signs and check the alert level first.
Which network does a Telcomia eSIM use in Guadeloupe?
Digicel, with 4G where available.
Is sargassum dangerous?
Rotting seaweed gives off hydrogen sulphide, which can be harmful near heavy strandings. Keep your distance and follow local notices.
The short version
From outside the EU, set up the eSIM before flying; check La Soufrière's alert level, stay off deserted beaches at night, wear repellent, watch your data on inter-island ferries, and keep 112 and 15 handy.
