Mobile roaming is the ability to make and receive voice calls and use data when travelling outside the geographic coverage area of your network. This means when you travel outside New Zealand and use your mobile phone you will incur additional charges.

Before you depart, discuss your travel plans with your mobile phone service provider. Whether you are visiting one or more countries, you can choose a mobile roaming package to suit. First, consider how you will use your phone abroad. Control how much you spend with a data cap. Also manage and monitor your usage with alerts to avoid unexpected costs.


Tips for reducing roaming data consumption:

  • Ensure data roaming is switched off before you depart, and only switch it on when you require it, to prevent background downloads and updates from using roaming data.
  • Check your phone settings only allow for app updates over WiFi connections.
  • Download a data usage monitoring app, to more accurately monitor accurate usage, and avoid bill shock.

To give you an idea of how much data you might use while roaming, have a look at the below table. These estimates are based on average Smartphone consumption using 3G network. Data usage will vary across devices and networks so these figures are to be used as guidelines only. Updated estimates for roaming over 4G coming soon.
