Endless mobile data explained: speed, limits and hotspots

Author: Jemesa Landers

The short answer

Endless mobile data means your data does not simply stop when you use your plan’s max speed allowance. Instead, your mobile data keeps working at a reduced speed until your next billing cycle begins.

That can be really useful for staying connected, especially for everyday things like messaging, email, maps and basic browsing. But it’s still worth understanding the difference between max speed data and reduced speed endless data, so you know what to expect from your plan. 

Coverage and actual speeds can vary depending on your location, device, network conditions and the plan you’re on. Always check Contact’s current mobile plan details and terms before choosing or changing a plan.

1. Max speed data and endless data are not the same thing

**Max speed data** is the data allowance you can use at the fastest speed available to you on the network. It is best for data heavy activities like high quality video, large downloads, gaming, video calls and hotspotting. 

**Endless data** is what you can keep using after that max speed allowance has been used. Your connection continues, but at a reduced speed. That means simple online tasks may still work well, while video, image heavy feeds, large downloads or hotspotting may feel slower. 

A simple way to think about it is: max speed data is for the things that need more power behind them and endless data helps keep you connected once that faster allowance is gone.

2. What happens when you use all your max speed data?

Once you use your max speed allowance, your mobile data automatically continues at the reduced speed included with your plan. You do not need to do anything for endless data to keep working. 

The experience may feel different, though. Messaging, email, maps and simple web pages may still be fine. Streaming, uploads, downloads, image heavy social feeds and video calls can take longer or may not work as smoothly. 

Your max speed allowance refreshes at the start of your next billing cycle. That may not be the same date a payment leaves your bank account, so check your account or the Contact mobile app if you are unsure.

3. How to choose the right max speed allowance

The best plan depends on how you use mobile data when you are away from Wi-Fi. 

Light use usually means messaging, email, maps, checking the weather, reading articles and occasional social media. 

Medium use may include regular music streaming, social media, browsing, app use and some video. 

Heavy use usually means frequent video streaming, gaming, large downloads, video calls or hotspotting to another device.
 

If you often use your phone as your main internet connection, watch lots of video on mobile data or rely on hotspotting, you may want a plan with a larger max speed allowance. 

Use trusted Wi-Fi for large downloads, app updates and software updates. Download shows, music, podcasts or maps before you leave home. Lower video quality when you are watching on a small screen, and turn off automatic app updates over mobile data. 

Your max speed allowance refreshes at the start of the next billing cycle, not necessarily on the day a payment leaves your bank account.

If you keep running out early

Review usage in the app, use Wi-Fi for data heavy tasks and consider a data add on if available. If this happens most months, compare the cost of add ons with moving to a plan that includes a larger max speed allowance.



Frequently asked questions


Does unused max speed data roll over?

Only if the current plan terms say it does. Check your plan entitlements and the current mobile terms.

Can I use my phone as a hotspot?

Hotspotting uses your mobile data and can use the max speed allowance quickly. Check your current plan terms to confirm hotspot availability and any conditions.
 

What network does Contact mobile run on?

Contact mobile is powered by the One NZ network. That means Contact mobile customers use One NZ’s mobile network for coverage, calls, texts and data. One NZ was awarded Best in Test in New Zealand by umlaut, part of Accenture, for voice, data and reliability in its June 2026 mobile benchmark. Coverage and speeds can still vary by location, device, plan and network conditions, so check Contact’s coverage map before choosing a plan.

Why is my mobile data slow?

Possible reasons include using all your max speed data, weak coverage, network congestion, device settings or a local fault. Check the app and Contact’s coverage information first.
