What 2degrees, One NZ and Skinny charge for data abroad
- 2degrees: on selected Prepay and Pay Monthly plans, Daily Roaming costs NZ$8 (US$4.53) a day and uses your plan's own data in Australia, Japan, the US, the UK and Fiji; after 1 GB a day at max speed, speeds drop to 128Kbps. A week costs 7 x NZ$8 = NZ$56 (US$31.74).
- Each day costs the same however little data you use that day.
- One NZ: on Pay Monthly, Daily Roaming costs NZ$10 (US$5.67) a day per device and uses your plan's data in Australia, Japan, the US, the UK and Fiji. A week costs 7 x NZ$10 = NZ$70 (US$39.67), and each day costs the same however little data you use that day.
- One NZ Prepay: the Weekly Prepay roaming Add-On costs NZ$22 (US$12.47) for 1 GB over 7 days and the Daily Prepay roaming Add-On NZ$6 (US$3.40) for 200 MB; a weekly Data Only Boost costs NZ$17.25 (US$9.78) for 1 GB. Each starts as soon as it is bought, and more can be added. One weekly boost and two Daily Add-Ons cover a median trip's 1.38 GB for NZ$29.25 (US$16.58); seven weekly boosts cover a 90th percentile trip's 6.50 GB for NZ$120.75 (US$68.43).
- Skinny: the 7 Day Roam Data Pack costs NZ$17 (US$9.63) for 1 GB in Australia, Japan, the US, the UK and Fiji, less than a median trip's 1.38 GB. Two packs hold 2 GB; a median trip uses 1.38 GB of them, so nearly a third of what you paid for is left unused.

2degrees, One NZ and Skinny roaming questions
How much is 2degrees roaming in Australia?
On selected Prepay and Pay Monthly plans, 2degrees' Daily Roaming costs NZ$8 a day in Australia and uses your plan's own data, so a week costs NZ$56.
How much is One NZ roaming?
On Pay Monthly, One NZ's Daily Roaming costs NZ$10 a day per device; on Prepay, One NZ's Weekly Prepay roaming Add-On costs NZ$22 for 1 GB and its Daily Prepay roaming Add-On NZ$6 for 200 MB.
How do I use a travel eSIM instead of 2degrees, One NZ or Skinny roaming?
Install the eSIM before you leave, set it as your data line, and turn data roaming off for your 2degrees, One NZ or Skinny line so it does not use data abroad. See turn roaming off on your home line.
With 2degrees and One NZ, making or answering a call or sending a text on your home line abroad also starts that day's Daily Roaming charge.
