3G is old technology. Shutting it down makes room for faster, more reliable 4G and 5G networks. While 3G technology has served us well for nearly two decades, by retiring 3G, mobile providers can free up valuable radio spectrum and resources to expand and enhance 4G and 5G services. This means more New Zealanders will benefit from better connectivity and innovative digital services.

To update your phone, make sure your phone’s software is updated to the latest version.
If you see a small VoLTE symbol at the top of your phone screen next to the signal bar, it means VoLTE is active. You don’t need to do anything, and your phone will continue to make calls after 3G is turned off.
Not every phone will display the symbol if VoLTE is active. If you don’t see it, look for an option to switch on VoLTE in your phone’s settings menu.
Apple: iPhones with iOS 14 or later use VoLTE by default, but you can go to Settings > Mobile > Mobile Data Options (or select your SIM) > Voice & Data to check 4G and/or 5G are on.
Samsung: Settings > Connections > Mobile networks. Switch on VoLTE calls.
OPPO: Settings > Dual SIM & Cellular Network (or ‘SIM card and mobile data’). Choose your SIM. Switch on VoLTE calls.
For further help, visit your provider’s website or contact them directly.

Before the 3G shutdown, mobile operators are upgrading 3G-only areas to 4G. The 4G and 5G networks are expanding rapidly across New Zealand to keep you connected and in most cases, you’ll enjoy an even better mobile experience.

4G coverage will match or improve on existing 3G coverage. However, at the edges of the network, coverage may differ slightly due to how the technologies work. Mobile operators will monitor these areas closely and are committed to supporting affected customers.
