From the end of 2025, beginning of 2026, New Zealand’s 3G mobile networks will be shut down. This is part of a global upgrade to 4G and 5G technology, which will free up valuable spectrum and will generally, ensure the delivery of more reliable mobile experience for consumers as well future-proofing connectivity. 

Any devices that rely on 3G technology in any way will no longer work after the shutdown. If your phone still relies on 3G for any service, calling etc., you will no longer be able to use that service post 3G shutdown (which may affect your ability to make 111 emergency calls).

In conjunction with mobile operators (OneNZ, Spark, 2degrees) and the New Zealand Telecommunications Forum (TCF), Samsung would like to reiterate the importance for Kiwis to check their phones or devices to ensure they are still compatible and will work after the shutdown. 

Samsung New Zealand have identified a number of older mobile devices that may not be able to connect 111 emergency calls once the 3G Network has been shut down. These devices may require a software update or need to be replaced, to make sure they work reliably in the unlikely event that help is required in an emergency.

Easiest way to check:

To determine if your device is 4G capable, users can text ‘3G’ to 550 to check you can stay connected post 3G shutdown. If your device isn’t ready, you may need to update your device settings or software, or upgrade to a compatible device.

Affordable options are available at Samsung.com/nz, network operators or retailers, and support are available to assist consumers through this transition. If you do have to upgrade, make sure you recycle your old device for free with RE:MOBILE or instore with your mobile network provider.

Customers that are impacted will have already received a notification from their mobile network provider with specific instructions based on the data they are able to obtain about each customer’s device. In some cases, you will have been told to contact the manufacturer of your device for further information. If you are currently using a Samsung device, please follow the instructions on this page.
