3G networks are switching off soon

New Zealand is retiring its 3G mobile networks soon, and we’re here to help you stay connected. 


Why is 3G shutting down?

3G networks are being phased out to make way for faster, more reliable 4G and 5G services. This includes the One NZ network that Contact mobile customers use. This upgrade means better coverage, speed, and performance for everyone.


What does this mean for you?

If you’re using a 3G-only phone, it’s likely that it will stop working after the shutdown. This means you won’t be able to make calls (including 111 calls), send texts or use mobile data after the network shutdown. 


When is the 3G network shutting down?

The network will be gradually phased out across New Zealand by the end of March 2026. Below are the currently scheduled shutdown dates for each area, but dates are subject to change.

What do you need to do?

To stay connected after the 3G network switches off, you will need a phone that’s able to use 4G calling (VoLTE). If your phone’s signal bar says 4G, 5G or VoLTE, then you should be all set. If it doesn’t then check out our list of common phones that support 4G


What to do next

If your phone doesn’t appear in our list, then it's likely that you will need to get a replacement 4G or 5G capable phone ahead of the network switch off. 

If your phone does appear in the list but you don’t think you are currently using 4G or 5G then you should check your phone settings to make sure that 4G/VoLTE is switched on.
