Connectivity in Milford Sound is notoriously limited to non-existent due to the steep fjord walls and remote location. Your CheapESIM will likely have very poor or no signal there. It is critical to download any cruise tickets, offline maps, and essential information before leaving Te Anau or Queenstown. While CheapESIM provides excellent value elsewhere, this area is a known dead zone, so plan accordingly and enjoy the unplugged natural beauty.
