You'll experience strong signal at the ports of Mindelo and Porto Novo. However, during the open ocean crossing between the islands, it's common for connections to drop. eSIM On Trip will keep you connected while docked, but be ready for intermittent service mid-journey. Enjoy the sea views, and reconnect once you approach land.
