WestESIM provides dependable signal in the town of Uyuni and at the historical “Train Cemetery,” allowing you to connect before and after your adventures. However, when you journey across the vast, remote expanse of the Salar de Uyuni itself and participate in multi-day jeep tours to the vibrant colored lagoons, expect very limited to no cellular coverage. The extreme remoteness of the salt flats makes consistent signal challenging, so plan for periods offline.
