Things to know about our 3G shutdown
In our quest to constantly improve our network, sometimes we need to wave goodbye to older technology. We, along with other mobile operators in NZ, are shutting down our 3G service towards the end of 2025. It's been a great run since 3G was introduced in 2009, but the future lies in the faster 4G and 5G networks. We're upgrading to make sure you're hooked up with top-notch connectivity!
You might already be using 4G for voice calls, also known as VoLTE in your network settings. If that's the case you're all set—no extra steps needed. Can’t see VoLTE on your phone? Read on to learn more about what this means and what action you need to take.

What is happening?
Towards the end of 2025, we'll be turning off our 3G network to enhance our 4G services and support the growth of 5G technology. We haven't sold 3G-only phones since mid-2022, they're just not flying off the shelves anymore, and we've noticed fewer customers using older phones on our network.
Many mobile operators worldwide, are starting to or have already shut down their 3G networks to make room for improvements to 4G and 5G networks.
What is VoLTE?
VoLTE stands for Voice over Long Term Evolution (LTE) which is another name for 4G. VoLTE allows you to make high-definition (HD) calls from a mobile using our 4G network.
Simply put, when you make a voice call over VoLTE, it connects faster and you can enjoy a clearer connection with reduced background noise. Learn more about VoLTE.
What do I need to do?
Over the remainder of this year and next year, 2degrees will contact all impacted customers directly to give them notice that this is happening.
If you are contacted you will have plenty of time to either upgrade your phone or device, or you may just need to turn on VoLTE in your phone settings.
How will I know if I have a compatible phone?
- You can check if you have a VoLTE enabled device.
- If you see VoLTE next to the signal bar at the top of your phone, then your device is VoLTE capable, and VoLTE is turned on.
- Using an iPhone or your phone does not display VoLTE? You can also check if VoLTE is available and enabled under your Settings.
How do I check or change my settings?
If you have checked your device is capable using the supported device list and your phone has been updated, you can check VoLTE is switched on in your settings.
iPhone:
iPhone: go to Settings > Mobile > Mobile Data Options > Voice and Data > Ensure 5G or 4G is ticked (dependent on phone capability) and that VoLTE toggle is enabled.
iPhone using dual SIM: (i.e. eSIM and physical SIM): go to Settings > Mobile > select the SIM you are using for voice calls i.e. Primary > Voice and Data > Ensure 5G or 4G is ticked (dependent on phone capability) and that VoLTE toggle is enabled.
Android:
Samsung: go to Settings > Connections > Mobile networks, ensure network mode is set as 5G or 4G auto connect (dependent on phone capability) and VoLTE calls are enabled.
Other Android: go to Settings > Mobile networks > select SIM, ensure network mode is set as 5G or 4G auto connect (dependent on phone capability) and VoLTE calls are enabled.
If the VoLTE option is not available when you go to your network settings your device likely will not support VoLTE.
Note: For Samsung, Oppo and other models dual SIM instructions should be the same as above.
What if my area only has 3G right now?
There are a small number of areas where only 3G is available today, we are working to expand our 4G coverage in those areas before we shutdown the 3G network.
What happens if don’t switch to a VoLTE capable phone?
You’ll need to upgrade to a VoLTE capable device if you want to stay connected after the 3G shutdown.
We offer a range of 4G and 5G ready phones in 2degrees stores. To upgrade to a new phone, jump online, or head into your nearest 2degrees store.
Can I use my phone overseas?
Mobile operators in some countries like the USA and Australia, are either starting to or have already shutdown their 3G networks.
From 28 October 2024, all 3G networks in Australia have shutdown. Without an up-to-date phone, you won't be able to use voice services while roaming. To avoid any issues, check your phone is VoLTE roaming capable before your trip.
