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.
