4G connectivity offers high-speed, low-latency mobile data for IoT solutions that require fast and reliable communication. It’s ideal for use cases like video surveillance, mobile EFTPOS, and vehicle tracking. To use 4G for IoT, your device must support 4G LTE and have a One NZ SIM with an appropriate IoT plan. Some devices may need a software update to operate optimally on our network.

LTE-M (Long Term Evolution for Machines) is a low-power wide-area technology built on our 4G network, designed specifically for IoT devices. It supports real-time data, mobility, voice, and TXT - all with extended battery life and better signal penetration for indoor and underground environments. To connect over LTE-M, your device needs to support LTE-M and use a compatible One NZ IoT SIM and plan.

NB-IoT (Narrowband IoT) is a specialised low-bandwidth technology designed for simple, stationary devices that send small amounts of data infrequently, think water meters, smoke detectors, and asset trackers. It provides deep coverage, long battery life, and efficient use of spectrum. Devices must be NB-IoT capable and use a One NZ IoT SIM and plan to connect to our network.

Voice over LTE (VoLTE) for IoT allows compatible devices to make voice calls over our 4G network. VoLTE enables clearer call quality, faster connection times, and improved battery performance for voice-enabled IoT devices such as medical alarms, in-vehicle systems, and remote monitoring solutions. To use VoLTE for IoT, your device must support VoLTE and be provisioned correctly on a One NZ IoT SIM and eligible plan. Some devices may require a firmware update or configuration change to enable VoLTE capability.

One NZ Satellite* extends your connectivity beyond traditional mobile coverage by connecting compatible devices with a clear line of sight to the sky directly to satellites. This uses the same 4G network technology (Cat-1) already built into many IoT devices.

Note: This coverage map is indicative only and is intended to provide general guidance on where the One NZ network and outdoor coverage is available. Coverage may vary depending on your exact location and the type of device used.
