New Zealand’s mobile networks are preparing to retire 3G, with shutdowns beginning at the end of 2025 and continuing into early 2026. Spark, One NZ, and 2degrees will all phase out their 3G services to make way for faster, more reliable 4G and 5G coverage.
While this upgrade promises better connectivity, it will also cause trouble for older devices and systems still reliant on 3G, especially older mobile phones, Medical Alarms or Burglar Alarm Systems, and business tools still relying on3G will stop working once the network is switched off.
An easy way to check if your device is affected by the 3G shutdown is by texting “3G” to 550. If your phone or system is affected, it’s time to upgrade.
Affordable 4G and 5G devices are widely available – including through SecureSphere – and old tech can be securely recycled through SecureSphere.
Rural areas like parts of Rangitikei may feel the impact more acutely, especially where 3G remains the backbone of mobile coverage. Businesses using IoT (Internet of Things) devices or legacy systems should act now to avoid disruptions.
The 3G shutdown is a wake-up call: future-proofing your devices is no longer optional.
SecureSphere is here to help support households and businesses through the transition because if your phone stops working, it’s not just inconvenient—it could mean losing access to emergency services when you most need them.
Whether you’re a business owner, a retiree, or a parent, now’s the time to check your tech and make the switch.
For help or advice, reach out to SecureSphere or visit your mobile provider’s website.
Let’s keep Marton and Rangitikei connected—and secure.
