While Milford Sound is undeniably stunning, it's also known for its extremely limited to non-existent mobile coverage due to the towering fjord walls. Your SouthESIM won't be your best friend here, so a practical tip for budget travelers is to prepare in advance! Make sure to download any cruise tickets, offline maps, and essential information before leaving Te Anau or Queenstown. Embrace the chance to truly disconnect and soak in the natural grandeur!
