What is CheapESIM's internet coverage in Patagonia (e.g., Torres del Paine and El Chaltén)?

In Patagonia, CheapESIM provides strong coverage in the main base towns like Puerto Natales, El Calafate, and El Chaltén, allowing you to plan your treks and stay connected. However, when you venture into national parks such as Torres del Paine or hike remote trails towards peaks like Mount Fitz Roy, signal strength will be very limited or non-existent. For budget-conscious travelers, this means relying on downloaded maps and enjoying the unplugged wilderness without incurring unexpected data roaming charges.
