When island-hopping in Cape Verde, particularly on the ferry crossing to Santo Antão, expect varying signal strength. eSIMFlyer will provide strong connectivity at the bustling ports of Mindelo and Porto Novo. However, during the open ocean transit between islands, signal drops are common. It's a great opportunity to disconnect and enjoy the sea views, but plan any essential online tasks for before or after your ferry journey.
