Yes. Coverage is excellent in the town of Deshaies and at the Botanical Garden, allowing you to share photos of the famous filming locations from the TV series instantly. 

 You will have strong 4G signal on the boat and at Malendure Beach. However, connection will naturally be lost once you submerge for diving or snorkeling at the Pigeon Islands. 

 Yes. The eSIM connects immediately upon docking at the Pointe-à-Pitre cruise port, allowing you to avoid expensive ship Wi-Fi and access maps for your day trip. 

 Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing. 

Yes, absolutely. Our eSIM connects to premium local networks (like Orange) that provide excellent 4G/LTE coverage not just on the main islands (Grande-Terre and Basse-Terre), but also on the popular day-trip islands of Les Saintes, Marie-Galante, and La Désirade. 

It is complicated.

• For EU Citizens: Yes, "Roam Like at Home" (RLAH) technically applies. However, many non-French carriers (e.g., from Germany, Spain) enforce strict "Fair Use Policies" for remote territories and may cap or throttle your data.
• For UK/US Citizens: No! Post-Brexit UK plans and all US plans will charge you very high international roaming fees ($10+/day).

A Cellesim eSIM guarantees a fixed price and high-speed data without "Fair Use" limits.

Yes, in most areas. You will have a strong signal at the base and in the main town of Basse-Terre. While hiking the La Soufrière volcano, the signal is surprisingly good on the trail but may drop at the summit due to weather/clouds. You will have a signal at all major beaches and towns, but expect "dead zones" if you go into the deep interior of the National Park. 

 This is the most critical question. This eSIM is valid for Guadeloupe and Martinique (as both are part of France/EU). However, it will NOT work in Dominica or Saint Lucia, which are independent, non-EU countries. Your connection will stop the moment the ferry gets close to those islands, and you will be charged high roaming fees if your home SIM takes over. For this multi-island trip, our Caribbean Regional eSIM is the only safe option.
