New Zealand eSIM
data from $3.49.

If you are searching for an eSIM for New Zealand, you can buy a data only plan from $3.49 and install it before you fly. Slashtel plans run on One NZ and Spark, the two networks most travellers rely on, with 5G where it is available. Your phone picks the network automatically when you land, so there is nothing to configure at the airport.

Choosing an eSIM for New Zealand

What matters is coverage on the main networks, enough data for your trip length, a validity window that matches your dates, hotspot support for a second device, and installing it before you leave. Price is only one part of the decision, and a cheap plan that runs out mid road trip costs you more in hassle than it saves.

Travellers often ask which is the best eSIM for New Zealand. There is no single answer, because a two week campervan circuit and a long weekend in Queenstown need different amounts of data. Work through these points instead:

• Coverage. A New Zealand eSIM should connect to the established networks. Slashtel uses One NZ and Spark, and your phone switches to whichever is available. You do not choose a network manually.
• Data amount. Sizes run from 1GB to 20GB. Map apps, photo backup and video calls all draw on your allowance, so match the size to your days on the road.
• Validity. Plans last 7, 15 or 30 days. The countdown starts when the plan activates, so buy for your actual trip length rather than a round number.
• Hotspot. If you carry a laptop or a second phone, check that tethering suits your plan. Hotspot use draws from the same data allowance.
• Installation timing. Add the eSIM to your phone at home, on reliable wifi, before you fly. Then it is ready the moment you arrive.

Sizes available are 1GB, 3GB, 5GB, 10GB and 20GB. Durations are 7, 15 and 30 days. All plans are data only, so there is no local phone number and no calls or SMS on the eSIM itself.

Networks and coverage in New Zealand

Slashtel New Zealand plans connect to One NZ and Spark, with 5G where those networks provide it, and the phone selects the network automatically. You do not need to change any settings on arrival beyond making sure the eSIM is switched on for mobile data.

Coverage varies by location, as it does on any network. Towns and cities such as Auckland and Queenstown generally have strong service. Remote stretches of the road, deep valleys and some backcountry areas can be weaker, which is normal for any mobile network in a country with this much open landscape. If you are planning a campervan route through remote areas, download offline maps and any bookings before you set off, so a gap in signal does not leave you without directions.

Because the network is chosen automatically, you do not have to think about which carrier your phone is using. Keep mobile data switched to the eSIM and leave data roaming on for that line, which is how travel eSIMs normally connect.

How much data you need

Match the data size to your trip length and how much you will use maps, photos and video calls. These trip types give a sensible starting point.

• One week: 1GB over 7 days. Enough for light use if you lean on wifi at accommodation.
• Two weeks: 3GB over 15 days. A reasonable fit for a shorter campervan route with daily map use.
• One month: 3GB over 30 days. Suits longer stays where most heavy use happens on wifi.
• Heavier use: 5GB, 10GB or 20GB over 30 days if you tether a laptop, upload photos and videos daily, or make frequent calls over data.

Think about how you travel. A campervan trip with navigation running all day, plus photo uploads each evening, uses more than a city break where your hotel wifi does the heavy lifting. Video calls over WhatsApp or FaceTime use data steadily, so factor those in if you check in with family often. If you run low, you can top up rather than buy a whole new plan.

Install it before you fly

Add the eSIM to your phone at home, on a stable wifi connection, and label it clearly so you can find it later. Installation takes a few minutes and removes the risk of landing in Auckland with no data and no easy way to get online.

Step by step guidance for both phone types is in our guide to installing an eSIM on iPhone and Android. Before you buy, it is worth confirming your handset supports eSIM at all, which you can check with is my phone eSIM compatible.

When you install at home, the plan does not start counting down until it activates on the network in New Zealand. Keep the eSIM switched off until you arrive if you want to be certain, then turn it on and set it as the line for mobile data. Leave your home SIM in the phone for calls and bank codes.

Calls, texts and your home number

The New Zealand eSIM is data only, with no local number, so calls and SMS do not run on it. WhatsApp, FaceTime and similar apps work over the data connection. That covers most of what travellers need: messages home, voice notes, video calls and checking bookings.

Keep your home SIM active for anything that needs your usual number, such as bank verification codes and calls to family on a normal line. Set the eSIM as the line for mobile data and your home SIM as the line for calls and texts. Turn off data roaming on the home SIM to avoid charges from your own provider, while leaving data roaming on for the eSIM so it can connect.

If your phone is dual SIM and supports two lines at once, this setup works well. You keep your number reachable and use New Zealand data for everything online.

Questions travellers ask about New Zealand

The answers below cover the points travellers raise most often before buying a New Zealand eSIM. If your question is about your specific handset, check the compatibility guide first.

Is the plan data only? Yes. There is no local number, no calls and no SMS on the eSIM. Messaging and calls through apps such as WhatsApp and FaceTime work over the data connection.

Can I use my home number for calls and codes? Yes. Keep your home SIM in the phone for calls and bank verification codes, and use the eSIM for data.

When does the plan start? The validity countdown begins when the plan activates on the network in New Zealand, not when you buy it. Install early and switch it on when you arrive.

Can I share data with a laptop? Hotspot use depends on your plan and draws from the same allowance, so choose a larger size if you plan to tether regularly.

Which phones work with it? Most recent iPhones and many Android handsets support eSIM. Check our compatibility guide before buying to be sure your model is supported.

Can I top up if I run low? Yes. You can add more data rather than buying a separate plan, which is useful on longer campervan routes where map use adds up.
