In Milford Sound, connectivity with Truly Roaming – and any provider – is extremely limited to non-existent due to the steep fjord walls creating a notorious "dead zone." It is crucial to complete any urgent work tasks, download your cruise tickets, and save offline maps before departing from Te Anau. Plan for a complete digital detox in this stunning, remote location.
