A travel eSIM works well in New Zealand, where three national networks, 2degrees, Spark and One NZ, cover the cities and main roads. The carriers also sell their own visitor plans, as a SIM or an eSIM. Two points are specific to the country: all three carriers have shut down 3G, and long stretches of road or trail have no signal. Check your home carrier’s international plan before you go: roaming charges depend on your plan.
This guide helps you choose and prepare for the coverage gaps. For the trip itself, see our New Zealand guide, when to go to New Zealand and our page on the NZeTA travel authorization.

eSIM in New Zealand: the essentials
- Three national networks: 2degrees, Spark and One NZ (Commerce Commission).
- 3G shut down by all three carriers (April 2026): your phone must work on 4G or 5G.
- Visitor plans: One NZ Travel SIM (shops at Auckland, Wellington, Christchurch and Queenstown airports); 2degrees Unlimited Travel SIM (up to 30 days per purchase).
- Coverage gaps: remote roads and sites; One NZ has offered a direct-to-mobile satellite service since December 2024.
- Emergency number: 111 (ambulance, fire, police), according to the UK FCDO.
How an eSIM works in New Zealand
An eSIM is a SIM built into the phone: you download a carrier profile by QR code or app. A travel eSIM is a prepaid data plan that runs on one of the three New Zealand networks; the provider’s listing says which. That network makes the difference on the West Coast of the South Island or in the national parks.
Is your phone compatible?
- eSIM: in settings, look for « Add eSIM » or « Add cellular plan ». The code *#06# shows an EID number on compatible devices.
- Unlocking: a phone locked to your home carrier will refuse another provider’s profile. Ask for it to be unlocked before you leave.
- Dual SIM: most recent phones keep your home line active for texts while the eSIM provides data in New Zealand.
- 4G required: since 3G was shut down, an old phone that only handles 3G, or does not support 4G calling, may not work properly; check 4G compatibility.
Three networks, and the end of 3G
The Commerce Commission, New Zealand’s competition and telecommunications regulator, says in its 2025 monitoring report (published 29 June 2026) that the country has three national mobile networks, operated by 2degrees, Spark and One NZ. It adds that by April 2026 all three had shut down their 3G networks, after extending 4G to replace 3G coverage as far as possible.
Coverage gaps and satellite
To fill coverage gaps, the public Mobile Black Spot Fund targets about 1,400 km (870 mi) of state highways and 168 tourist sites that had no coverage; it is delivered by the Rural Connectivity Group, a joint venture of the three carriers. The Commission also notes the arrival of direct-to-mobile satellite services: One NZ launched the first national service in December 2024, initially limited to text messages. These services depend on the carrier and the phone: with a travel eSIM, do not count on them.
The U.S. State Department notes very limited cell phone coverage on large portions of scenic highway in the South Island, which is remote and has little traffic (travel.state.gov, last updated May 7, 2026). It also says that New Zealand’s National Emergency Management Agency broadcasts Emergency Mobile Alert messages from local cell towers to all capable phones in the area for serious threats to life, health or property. For hikes out of network range, take a suitable way to call for help and leave your itinerary with someone; the State Department advises never doing adventure sports alone, carrying identification and letting someone know where you are, and the New Zealand Department of Conservation website gives advice on hiking safely.
Carrier visitor plans

What should you choose?
- Road trip of two to three weeks: a travel eSIM installed before departure, or a carrier visitor plan if you want a local number to book campsites and activities.
- Stay of more than a month (working holiday): a local prepaid line becomes more practical.
- Phone without eSIM: physical SIM, as long as it works on 4G.
- Your home carrier’s roaming: only with a suitable add-on; check your plan’s international terms and charges first.
Installing your eSIM step by step
- At home, check eSIM compatibility and that the phone is unlocked.
- Buy the plan and note when validity starts: at installation or at first connection on site.
- Install the profile on Wi-Fi (QR code or app) and label the line « New Zealand ».
- On arrival, choose this line for cellular data, turn on data roaming on this line only if the provider asks, and turn off data on your home line.
- Keep your home line active for text messages such as bank codes, after checking that receiving them abroad is not charged.
Common mistakes to avoid
- Leaving with an old 3G phone: the 3G network no longer exists.
- Counting on the network for a hike or an isolated pass.
- Buying the 2degrees Travel SIM for a trip that includes Australia: it only works in New Zealand.
- Installing the profile on arrival, without Wi-Fi: do it before departure.
- Forgetting to turn off data on your home line: it is the one that would bill roaming.
- Deleting the eSIM profile during your stay: many cannot be reinstalled.
Buying an eSIM for New Zealand
To choose, compare the New Zealand network used (2degrees, Spark or One NZ), the data volume, the validity period, when it starts, tethering, whether you can top up, and whether there is a local number. A « data only » eSIM is enough for most travelers: messaging apps replace calls. Offers and prices change often: check the provider’s listing on the day you buy.
