How does eSIMAdventures perform in the Australian Outback (like near Uluru) and New Zealand's Milford Sound?

Updated April 22, 2026

Coverage in truly remote areas can be challenging, even for the best networks. Near Uluru, you'll generally find service around the main resort areas and visitor centers, perfect for sharing that iconic sunrise shot. However, deep within the Australian Outback or the dramatic fiords of Milford Sound, connectivity becomes sparse due to extreme terrain and limited infrastructure. For Milford Sound, we strongly advise downloading all maps, tour tickets, and essential information offline before entering the region. eSIMAdventures helps you prepare for these off-grid moments with our offline prep guides.
