DataESIM provides consistent 4G LTE signal within the town of Uyuni and at the immediate vicinity of the Train Cemetery. This ensures connectivity for initial logistics and communication. However, the vast, expansive terrain of the Salar de Uyuni itself, particularly during multi-day jeep expeditions to remote areas like the colored lagoons, presents significant challenges for cellular infrastructure. Consequently, reliable data coverage is extremely sparse or non-existent across the majority of the salt flats, consistent with the remote nature of the region.
