New Zealand is saying goodbye to 3G. Are you ready for the change?

Brian from Mount Roskill

1. What’s happening?
From the end of 2025, beginning of 2026, New Zealand’s mobile operators (2degrees, One NZ and Spark) will shutdown their 3G networks.

2. Why is 3G being shutdown?
3G is old technology. This is part of a global upgrade to 4G and 5G technology, to deliver a more reliable experience for consumers and future-proof connectivity.

3. Why does this matter?
3G-reliant phones, tablets, alarms and business/IoT devices will no longer work after the shutdown.
Most New Zealanders already use 4G or 5G devices, but if you’re unsure, it’s important to check.
Some 4G phones still use 3G for voice calls, and may require changes to settings to default to 4G networks.
Affordable, compatible devices are available, and support is available for those who need it.

4. Who is affected?
Anyone using a 3G-reliant phone, tablet, medical alarms, security alarms, business equipment, vehicle trackers and other IoT devices.

Most New Zealanders already use 4G or 5G devices, but if you’re unsure, it’s important to check your device now.

5. How can I check my phone?
FREE-TXT ‘3G’ to 550 to check you can stay connected.

6. What do I do if my phone isn’t ready?
If action is required, your provider will guide you through your next steps.
You may need to update your settings or software, or upgrade your device. Affordable options are available, speak to your provider about your needs.

7. How do I update my phone to use 4G/5G?
To update your phone: make sure your phone’s software is updated to the latest version.

To turn on 4G/5G in your settings:
iPhone: Settings > Mobile > Mobile Data Options > Voice & Data > Select 4G/5G
Android: Settings > Mobile networks > Enable 4G/5G

8. Do I need a new SIM card?
If your SIM card isn’t 4G capable, you may need a new one.
Your provider can help you transfer your number to a new SIM if needed.

9. What if my device was bought overseas?
Some imported devices may not work on New Zealand networks, even if they are advertised as 4G.

FREE-TXT ‘3G’ to 550 to check.

10. What other devices are affected?
Any other IoT devices that rely on 3G will stop working after the shutdown.
This includes some tablets, smart watches, medical alarms, security alarms, and other business devices.
Please contact your device supplier to confirm if your device is affected.

11. What about emergency calls?
3G-reliant devices will not be able to make any calls, including to 111, after the shutdown. It is critical to check and update or upgrade your device so you can contact emergency services.

12. If I need to upgrade, can I recycle my old phone?
Yes, you can recycle your old phone for free with RE:MOBILE. There are free-post options, or over 500 drop-off locations across Aotearoa.
