Experiencing 4G dropped calls?
Our mobile network utilises various frequencies to deliver comprehensive 4G and 5G coverage. One of our 4G frequencies (Band 28B) is specifically designed to extend coverage in rural areas and penetrate deeper into buildings in urban settings. However, some older 4G phones, those purchased from overseas or parallel imported may not support this frequency. If you own one of these phones, you might experience reduced 4G coverage, leading to more frequent use of 3G or an increase in dropped calls. To resolve these issues, we recommend upgrading to one of our current models.
- If you have a One NZ pay monthly mobile plan, consider buying a new phone interest-free. Check out your phone options .

For visitors coming to New Zealand - if your mobile phone operates on one of these same frequencies and it is not locked to your home network, you should be able to use your phone on our network.
You can check with your home-country service provider before you leave. If you have been set up to Global Roam to New Zealand you will be able to switch on your mobile and use it here.
