Will DataESIM maintain signal on the ferry to Santo Antão, Cape Verde?

DataESIM provides strong signal coverage within the port areas of Mindelo on São Vicente and Porto Novo on Santo Antão. However, during the open-ocean transit between these islands, expect a reduction in signal strength and potential connection drops. Cellular networks are primarily land-based, and coverage diminishes significantly offshore. While some intermittent connectivity might occur closer to either island, continuous data services cannot be guaranteed during the main ferry crossing.
