Will I have signal on the inter-island ferry to Santo Antão, Cape Verde?

CoreESIM users can expect strong signal at the departure port of Mindelo on São Vicente and upon arrival at Porto Novo on Santo Antão. During the open ocean crossing between these islands, however, mobile data connectivity will likely become intermittent or cease entirely. This is a common characteristic of maritime travel beyond coastal cellular reach. Signal typically resumes as the ferry approaches the destination island and re-enters network coverage areas.
