How good is the Dominica cell service for tourists in remote areas like the Boiling Lake trail?

Our eSIM connects to the FLOW network, which offers the best available coverage in Dominica. While service is strong in towns and coastal areas, you may experience intermittent or limited signal in extremely remote, mountainous regions like the Boiling Lake trail due to the island's challenging terrain. It is always wise to download offline maps as a backup for such excursions.
