With the rollout of 4G and 5G across New Zealand, Mighty Mobile's 3G network is being shut down on December 31st 2025. Mighty Mobile is powered by the One NZ network.
By December 31, 2025, you'll be able to access 4G everywhere that you currently access 3G, with even faster 5G access available in certain areas.
To find out more about the 3G switch-off, and to check if your device is 4G/5G compatible, we'd recommend checking out One NZ's 3G switch-off page.
