Unlimited talk and texts are now pretty standard across all mobile phone plans $40 and over, and data has become the real deal-breaker. Whether you're video calling or streaming, Googling, TikToking, gaming or social-media scrolling, ample data is required to go the distance.
It's therefore no surprise that connectivity and endless data plans have become the core focus of telcos' offerings. However, while unlimited data phone plans mean you'll never be without data, there are often speed caps involved:
In the following guide, we take a look at the range of endless data plans on offer from:
- 2degrees
- Kiwi Mobile
- Mighty Mobile
- Nova Energy
- One
- Rocket Mobile
- Skinny
- Spark
Plus we explore the data speeds you can expect, and some of the key terminology and what to keep in mind when shopping around for an endless data mobile plan. All prices correct as of 07/01/26.
2degrees' endless data plans
2degrees has two unlimited data plans:
Monthly plan
- $80 Plan: Endless data (no max speed cap) & unlimited calls & texts to NZ/OZ. Add group plans for $40/m.
Prepaid monthly plan
- $85 Plan: Endless data (no max speed cap) & unlimited calls & texts to NZ/OZ
Both plans offer hotspotting, free voicemail and are 5G ready.
Kiwi Mobile's endless data plans
Kiwi Mobile's two phone plans deliver unlimited data, capped at download speeds of of 1.2Mbps once you hit one of five data caps. The plans are unique because once you hit your data cap, if you don't want your data speed slowed to 1.2Mbps, you can opt to move up to the next data tier. You can do this manually through the Kiwi Mobile app, or do it automatically. If you opt to increase your data limit, the daily cost of your plan rises accordingly for those days of additional data.
However, whatever data/price tier you end up on by the end of the month, when the next billing cycle comes around (there are 12 per calendar year), your plan automatically resets back down to your original plan.
Choice Lite Plan
Data Tiers | Cost |
|---|---|
1GB | $0.59/day ($17.95/m) |
1.5GB | $0.89/day ($27.07/m) |

Which plan should you sign up for?
The best plan for you depends on your phone usage. However, as long as you don't sign up for a fixed-term plan, it's easy to shop around and swap plans and/or providers if your needs change.
If you want truly unlimited max-speed data, there are six choices:
- 2degrees: $80/m & $85/m
- Mighty Mobile: $80/m
- One: $85/m
- Rocket Mobile: $75/m
- Skinny: $70 per four weeks
- Spark: $90/$95/m
Of these, over 12 months, Rocket Mobile has the best price, which gets even better if you apply the group discount, reducing the cost to $50 per month per person.
Also, 2degrees allows you to add up to five group plans for $40/m per plan, and with Spark you can add up to five group plans for $45/m per plan – meaning average prices drop the more people you add.
And although Spark's two plans are the most expensive, for that price you do get either free Spotify Premium ($18.99) or Netflix Standard ($25.99/m), which is great value.
Ultimately, the best plan for you has to suit your budget and your data needs. So before you make a choice, it's a good idea to review your recent data usage to ensure you don't end up paying for more data than you need.

Endless data speeds
As we mention above, endless data plans might offer unlimited downloads, but on most plans speeds are often capped, usually to speeds of around 1.2Mbps, once a data limit is reached. While this limit is fast enough for streaming music and surfing the internet, it's not suitable for video streaming or video calling:
- Netflix recommends a download speed of 3Mbps per stream for playing SD-quality TV shows and movies, 5Mbps for HD and 25Mbps for UHD
- For HD video calling download/upload speeds of around 1.5/1.5Mbps are required
Overall, 1.2Mbps is a crawl compared to average 4G speeds. According to the latest Opensignal Mobile Network Experience Report, which analyses global phone network speeds, the average download speeds available on the three big mobile networks in NZ are:
Average 4G download/upload speeds
- One: 62/11Mbps
- Spark: 58/9Mbps
- 2degrees: 51/12Mbps
Average 5G download/upload speeds
- 2degrees: 343/32Mbps
- One NZ: 313/25Mbps
- Spark: 262/21Mbps
Key terms to help you compare endless data mobile plans
Some terms you'll likely come across include:
- Open-term plan – is a plan with no fixed-term contract commitment (such as a 12- or 24-month commitment). This means that while you pay monthly, you can exit or change your plan at any time without incurring a cancellation fee.
- Endless data – this is a mobile plan that comes unlimited phone data. However, typically, it comes with a maximum speed data allocation, with internet speeds reduced (but unlimited) once this allocation has been exhausted (typically to 1.2Mbps).
- Hotspot – this allows you to wirelessly share your smartphone's internet connection with other devices, as if it's a wi-fi modem. Some providers may cap your hotspot data usage or charge an additional monthly fee to use hotspotting.
- Unlimited talk and text – typically applies to standard New Zealand and Australian numbers. However, keep in mind that not all numbers will be covered.
- Group plans – usually comprise a primary plan (which customers initially sign up for), with the option to then add companion plans (often up to five additional plans) for a discounted rate. The more companion plans added, the lower the per-person cost per billing period.
- MB/GB – data allowances are measured in MB and GB. It is worthwhile weighing up how much data you require from one month to the next, and whether reduced speeds will suffice.
- Mbps – stands for megabits per second, which is the measurement of your internet speed. Average 4G/5G mobile speeds can vary depending on a range of factors, but keep in mind that reduced speeds of 1.2Mbps will be significantly slower.
- Auto-renew – some mobile plan add-ons will auto-renew, meaning they'll automatically be added to your bill each month. Remember to cancel the add-on if you're purchasing it as a one-off.
