WestESIM provides strong signal at the departure and arrival ports of Mindelo (São Vicente) and Porto Novo (Santo Antão). During the open ocean crossing between these islands, however, you should anticipate potential signal interruptions. While land-based coverage is robust, the vastness of the Atlantic can affect connectivity. We recommend handling any urgent communications before or after the ferry journey.
