Mobile data is delivered to your phone over a mobile network, distinct from your WiFi connection at home.
Mobile data lets your phone connect to the internet, powering your Apps, email refreshes, your weather updates, and downloads.
If you run out of mobile data, you might experience slower speeds, or pay extra.

• Video, music, and updates use the most data - TikTok, Youtube, Instagram.
• Apps running in the background can use data without you realising it.

Almost all of the Apps on your phone will use data at some point, and some will use a lot more than others. Some Apps will use data while you're actively using them, and some Apps will still use data while they're running in the background.

Data on your phone plan gets used when you browse websites, stream music, use social media, and get used by Apps. The amount of data that's used depends on each kind of activity. Simply checking your email and some web-browsing might use a small amount of data, while videos on YouTube, TikTok, and Instagram are likely to use a lot more.

To help you understand file sizes, a standard quality song on Spotify might be around 3MB. The same song at very high sound quality might be 10MB in size.

Most mobile plans have a data allowance, which is the maximum amount of data you can use during a billing period.

If you don't want to worry about that, our One Plan includes unlimited data, so you don't need to think about your usage.

For plans that do have a limit, once you reach your max speed allowance, you may be charged casual rates on older Prepay plans, or you might experience reduced speeds on some Pay Monthly plans.

Remember that how your Apps use data is all within your control. You can reduce data usage by using WiFi and turning mobile data off.
Did you know you can restrict access to mobile data for individual Apps? This can be done in iOS - and in Android.

You can also get more data if you need it, so check the My One NZ App for a Max Speed Data Boost, or an Unlimited Burst Add-On for Prepay Plus.
Look through our Add-Ons for Pay monthly.

1. Track your usage regularly. Use our My One NZ App or sign in to My One NZ to understand your usage.
2. Get to know how much data, calling minutes and TXTs are on your plan. Knowing your limits will help you to avoid going over them. Find your plan’s allowance by signing into the One NZ app.
3. Use WiFi whenever you can. Make your mobile data last longer by using WiFi wherever you can. You can even use WiFi Calling to make and receive calls in any location covered by WiFi, both here in NZ, and when travelling overseas.
4. Turn off background data and delete your unused apps. Many apps will use data in the background, even when you're not using them. So you can force-close Apps if you want.
5. Be aware of data roaming charges. Data roaming charges can be expensive. So if you're traveling outside of New Zealand, be sure you know about the data roaming rates.

To stay in control, check your data usage in the My One NZ app, adjust your phone settings to suit you, and add more data when you need it.
