While SouthESIM provides excellent 4G/LTE coverage in Dominica's main towns like Roseau and Portsmouth, and around popular spots like the cruise ship port, coverage can become limited in remote hiking areas. Dominica is a rugged, mountainous 'Nature Isle,' and once you venture deep into the rainforests or embark on trails to locations like Boiling Lake, you might find the signal intermittent or absent. We recommend downloading offline maps and essential information before heading out for those deeper adventures.
