WorldESIM users can expect reliable signal in the town of Uyuni and often at the initial points of interest like the Train Cemetery. However, as your tour progresses onto the immense, otherworldly expanse of the Salar de Uyuni itself, and especially during multi-day expeditions to remote lagoons and geysers, connectivity becomes extremely scarce. This is a perfect opportunity to disconnect and fully immerse yourself in Bolivia's stunning natural landscapes.
