Skip international roaming ($15/day) at Queenstown Airport arrivals - Vodafone, Spark, and 2degrees counters offer tourist SIMs from $19/week with unlimited data. Essential for booking Shotover Jet online, tracking Orbus buses via Transit app, and making dinner reservations at Rata or Fishbone.

Coverage works perfectly around Lake Wakatipu, through Arrowtown's historic goldfields, and surprisingly well on the Glenorchy-Paradise road to LOTR filming locations. Signal holds strong up Coronet Peak and most Remarkables ski runs during winter season.

Critical for road trips: 2degrees $29 plan includes unlimited social media plus 3GB high-speed data. Download offline maps before tackling Crown Range Road to Wanaka - cell towers vanish in those Southern Alps valleys. Works better than most Queenstown accommodation wifi, which crashes whenever someone microwaves their Fergburger leftovers.
