How do pay monthly plans work? 

A pay monthly plan is an agreement between you and the mobile provider. You pay a set amount each month to access the network and use the services included in your plan, like calls, texts, and data. Generally, you pay a fixed cost for a specific allowance of gigabytes (GB) and minutes. As long as you pay your bill, the plan stays active until you decide to cancel.

When you sign up, you’ll receive a SIM card (or an eSIM) to pop into your own phone. This means you don’t need to buy a new mobile to get these deals—you’re just paying for the connection.

How do I find the best pay monthly plan for me?

  • Check network coverage. NZ geography can be tricky. For your mobile to work reliably, the provider needs good reception where you live, work, and play. Most NZ providers have coverage maps on their websites – check the signal strength at your address before signing up.
  • Choose data that matches your usage. Data inclusions vary between providers. Some offer modest data packs, while others offer “endless data”. Start by checking your current usage history. It’s usually easy to upgrade or change your plan later if your habits change.
  • Check the support channels. If you prefer talking to a real person when you have an issue, make sure the provider has a customer service hotline. Some lower-cost brands (MVNOs) operate entirely online with chat support only.
  • Pick the plan with the best value. Prices vary significantly. You can often save a fair bit of cash by comparing offers rather than just sticking with the big names. Use the table at the top of this page to quickly find a provider that fits your budget.

How to sign up for a pay monthly plan

  1. Compare the offers in the table above and pick the one that suits you.
  2. Visit the provider’s website to sign up.
  3. Choose your SIM type: Physical SIM or eSIM (if your phone supports it).
  4. Enter your details: You will need a valid ID, such as a New Zealand Driver Licence or a Passport.
  5. The provider will run a credit check. This is standard for pay monthly plans in NZ.
  6. If approved, they’ll send the SIM to your address (usually takes 2-4 working days). If you have chosen an eSIM, you’ll get a QR code via email to activate it immediately.
  7. Once your SIM arrives, pop it in your device and start using your new plan. If the provider has a mobile app, download it to track your data usage and manage bills easily.

Are there plans with endless data? 

Yes, most major providers in New Zealand offer plans with endless data. However, it’s important to understand how these work: you typically get a generous amount of data at max speed (e.g., 40 GB or 100 GB). If you exceed this cap, you won’t be charged extra or cut off. Instead, your speed reduces (usually to around 1.2 Mbps). This is still fine for browsing and Spotify, but HD video might buffer.

Tip: Always check the provider’s “Fair Use Policy” to see exactly where the max speed limit sits.

Hotspotting limits 

Some Endless Data plans have restrictions on “hotspotting” (tethering your laptop or tablet to your phone). Check if your provider counts hotspot data towards your max speed limit or if there is a separate cap to avoid surprises.

Can you get a plan with an open term? 

Yes, many NZ providers offer open term plans. This means you aren’t locked into a long contract and can usually cancel or change your plan with just 30 days’ notice.

The main advantage is flexibility. However, if you are willing to sign a fixed term contract (usually 12 or 24 months), you might score a better monthly rate or a subsidy on a new phone.

Please note: Notice periods still apply 

Even on an open term plan, standard practice is to give the provider 30 days’ notice if you want to leave.

Can I use my plan overseas? 

Yes, but unlike in the UK or Europe, using your NZ plan overseas is rarely free. Most major providers (like One NZ, Spark, and 2degrees) offer a “Daily Roaming” service. This lets you use your home plan’s minutes and data in popular destinations (like Aussie, the UK, and the USA) for a fixed daily fee (usually around $8 per day).

  • Tip: Roaming triggers automatically when your phone connects to a foreign network.
  • Warning: If you travel to a country not covered by the daily roaming deal, costs revert to “casual rates,” which can be very expensive. Always check the provider’s roaming list before you fly.

How do I switch providers? 

If you want to switch, check your current contract status first (usually found in your provider’s app). If you’re on a fixed term, you might face an “Early Termination Fee”.

You can choose to keep your number when signing up with the new provider – just tell them you want to bring your number (this is called porting). You’ll receive a text message to confirm the switch. The new provider handles the break-up with your old telco, so you generally don’t need to call to cancel.
