Saint Kitts and Nevis is served by two main mobile operators: Flow Saint Kitts and Nevis and Digicel Saint Kitts and Nevis, both providing 4G LTE coverage across Basseterre, Frigate Bay, and the main populated and tourist areas of Saint Kitts. Nevis has coverage in Charlestown and the main coastal areas, with signal becoming less consistent on the higher slopes of Nevis Peak. The rainforest interior and volcanic highlands of both islands may have weaker signal depending on elevation and terrain. The ferry crossing between the two islands takes around 45 minutes and has variable coverage depending on sea conditions and position. MobiSIM connects through supported local networks to deliver reliable data across both islands' main tourist and coastal areas.
