When you're in the town of Uyuni and visiting popular spots like the 'Train Cemetery,' your SouthESIM should connect you just fine. However, once your jeep tour heads out onto the vast, otherworldly expanse of the Salar de Uyuni and into the remote multi-day routes exploring the colored lagoons, expect minimal to no signal. It's a truly remote landscape, so be prepared for some digital detox while you soak in the incredible scenery!
