With WorldESIM, you'll experience strong signal at the ports of Mindelo on São Vicente and Porto Novo on Santo Antão, allowing you to connect before and after your ferry journey. During the open ocean crossing between these islands, however, expect your connection to become intermittent or drop entirely. This is typical for maritime travel. We recommend planning for periods without internet access and enjoying the scenic views of the Atlantic.
