#business: Telcos Urge Kiwis to Check Phones as 3G Shutdown Risks Loss of 111 Access

New Zealand telecommunications companies are urging people to check their mobile phones to ensure they will still be able to contact emergency services as the country’s 3G networks are switched off.

The warning comes as the telecommunications sector continues the nationwide shutdown of older 3G mobile technology, part of a global shift toward faster and more reliable 4G and 5G networks. The final stages of the shutdown are expected to be completed by the end of March 2026.

Industry groups say most people already use 4G or 5G devices and will not be affected. However, some older phones and other connected devices still rely on 3G technology and will stop working once the network is switched off.

That includes the ability to make emergency calls.

Devices that depend on 3G will no longer be able to make any calls, send text messages or use mobile data after the shutdown. Critically, those devices will also be unable to dial New Zealand’s emergency number, 111.

Telecommunications providers are encouraging customers to check their devices as soon as possible to ensure they remain connected. One way to do this is by sending a free text with the word “3G” to the number 550, which allows users to see whether their phone will continue working once the old network is retired.

The industry says the transition is necessary because 3G technology is now outdated and maintaining it limits the ability to expand newer networks. Reallocating those frequencies will allow providers to strengthen 4G coverage and expand 5G services across the country.

The shutdown may also affect other devices beyond mobile phones. Medical alarms, security systems, vehicle trackers and some tablets that rely on 3G connectivity could stop functioning once the network is retired.

Telecommunications companies say people should also check devices used by whānau members who may be more likely to rely on older technology, particularly elderly relatives.

Emergency calls to 111 remain a critical safety service in Aotearoa, handling hundreds of thousands of calls each year for police, fire and ambulance assistance.
