Cabo Polonio is known for its rugged, off-grid nature, and while connectivity is a challenge due to its lack of a conventional electricity grid, eSIM Trails aims to provide what's available. Expect limited but present 4G coverage, primarily outdoors and often strongest near prominent points like the lighthouse. Be prepared for intermittent service as you explore this unique, remote Uruguayan gem.
