WHAT IS WIRELESS BROADBAND?

Wireless broadband uses the 4G mobile network instead of underground copper or fibre cables, making it a great alternative if fibre isn’t available at your address. It runs on the same technology your mobile phone uses to connect to the internet.

With 4G coverage across most of New Zealand, Mercury’s wireless broadband is quick to set up and includes a router with every plan—so you can plug in and get online fast.

4G wireless broadband is generally faster than ADSL copper connections, though not as fast as fibre. Actual speeds can vary depending on your home’s location, router placement, device age, number of connected devices, and overall network traffic.

1,000GB and 300GB data plans run at maximum speed to data threshold, then are throttled to 5Mbps until the plan renews. 120GB plan is capped and once data cap has been reached, service will stop until the plan renews, unless data packs are purchased to continue service at maximum speed.

Add-Ons and Auto Allowance Packs (120GB Plan Only)

If you have a capped wireless broadband plan and use up your monthly base plan data, to keep you online you will have one 10GB extra data pack automatically added and charged to your account. If you use all your base plan data as well as this additional Auto Allowance, your broadband service will stop (until your monthly plan renews) unless you top up manually with an Add-On pack. We recommend purchasing Add-On pack when needed as they provide you with great value for money. They need to be manually purchased by you and do not automatically renew each month. Check out the packs available below. It’s easy to add or remove a pack with the Mercury app. You can download our app from the app store. From there, simply head to the Broadband section within the app to manage your Wireless Broadband plan.
