WestESIM aims to provide robust coverage, even along picturesque coastal routes such as California's Pacific Coast Highway (Highway 1) or the stunning Amalfi Coast in Italy. While coverage is generally strong in these popular tourist areas, you might encounter brief, intermittent signal drops in very secluded coves or areas with dramatic cliff formations. To ensure uninterrupted navigation and enjoyment of your journey, we strongly advise downloading offline maps for your route via Google Maps or Apple Maps before you depart from major urban centers like San Francisco or Naples.
