Useful travel information
A few details that help before and during your trip.
Mobile coverage in Dominica
Dominica's mobile network is served by two main operators: Flow Dominica and Digicel Dominica, both providing 4G LTE coverage across Roseau, Portsmouth, and the main coastal towns. Dominica is one of the most mountainous islands in the Caribbean, and coverage in the interior rainforest, volcanic highlands, and remote valley areas can be significantly weaker or absent depending on terrain and distance from transmitters. The Morne Trois Pitons National Park, Boiling Lake trail, and Waitukubuli National Trail pass through areas with very limited signal in several sections. Coastal villages generally have more reliable connectivity than inland jungle and highland zones. MobiSIM connects through supported local networks to deliver reliable data across Dominica's main populated and coastal areas.
eSIM tips for Dominica
Activate your MobiSIM eSIM before your flight so you are connected on arrival at Douglas-Charles Airport or via ferry at Roseau Cruise Ship Berth. Download offline maps for Roseau, Portsmouth, Morne Trois Pitons National Park, and the Boiling Lake trail before travelling, as rainforest and highland areas have very limited signal. Keep your home SIM active for calls while MobiSIM provides your data connection. Dominica is known as the Nature Isle of the Caribbean and most of its best attractions are deep in the rainforest, so treating inland areas as largely offline and preparing all trail maps, guide contacts, and lodge details before setting out is strongly recommended. If you are arriving by cruise ship for a day visit, activate your eSIM before docking so you have navigation and information access from the moment you step ashore in Roseau.
