What is the expected DataESIM coverage in remote Australian and New Zealand regions like Uluru and Fiordland?

DataESIM's coverage extends to many remote, yet accessible, areas. At Uluru-Kata Tjuta National Park, particularly around the cultural center and resort infrastructure, you will typically find reliable data access. However, in geologically challenging areas such as New Zealand's Fiordland National Park, including the deep fiords around Doubtful Sound, connectivity can be limited due to terrain and infrastructure constraints. For these specific locales, we recommend pre-downloading critical data, such as high-resolution maps or itinerary documents, to your device before venturing into areas with known signal attenuation.
