About One Number

One Number from Spark is a way to use your phone number on your phone and your cellular watch. Two devices, one number. You can also make and receive calls and SMS from your watch without being close to your phone.

You can get One Number when you sign up for a $7.00 One Number Wearable Plan ($6.09 excl. GST). It's a plan for cellular watches only. It lets you use the minutes and SMS from your primary Spark Pay Monthly mobile plan on your watch. Plus, you always get endless data on the watch. 

Note: Endless speeds reduce to 1.2 Mbps after max speed data allowance exceeded. No tethering or hotspots. You can only get SMS messages if your iPhone is turned on and connected to the network. 

What you'll need

To get One Number, first you'll need a smart watch and phone. Check your device compatibility:

Apple Watch

  • Apple Watch Series 3 (GPS + Cellular) or later (on the latest software version) 
    • To check if there is a software update available, from your iPhone open the Watch app. Tap General > Software Update. You'll need watchOS 6.1.1 or later. Before installing an update, we recommend  performing a backup. Download the update over WiFi to avoid using data.

You can also perform a software update from the watch: How to perform a software update

Note: The Spark network doesn't support models from the North American region. Learn more about bands, supported locations and carriers at apple.com/nz/watch/cellular

Here's how to install the latest software (iOS) from Apple:

  1. On your iPhone, go to Settings > General > Software Update.
    • Before installing an update, we recommend backing up your phone. Download the update over WiFi to avoid using data.

Frequently asked questions (FAQ)

Get answers to common questions about Spark's One Number Wearable Plan.

When you activate your One Number plan from your watch, Spark picks up your primary mobile number and associates it with your wearable device. So whenever you get a call, the network routes the call to your primary mobile number. This means that both your watch and phone will ring.

See step-by-step instructions:

When you make a call or send a text from your watch, your contacts will be none the wiser. People on the other end of your calls and texts will see your primary mobile number. That's it.

The $7.00 One Number Wearable Plan is billed just like your Spark Pay Monthly plan. Your One Number plan will appear underneath your primary mobile number. You can see an example of a bill with One Number here:

Example of Spark bill with One Number Wearable Plan

Your watch uses the voice minutes and text message limits of your primary plan. For example, if you have the $39.99 Pay Monthly plan with 300 minutes each month, any calls you make from your watch will subtract from these minutes. You can check your detailed usage at any time on the Spark app or online at spark.co.nz/myspark

The cellular features of Apple Watch include reading and replying to text messages, calling and streaming Apple Music. To use these features, you'll need to sign up for the One Number Wearable Plan with Spark. 

This plan is a Pay Monthly plan that's billed on top of your primary Pay Monthly mobile plan. It costs $7.00 per month ($6.09 excl. GST).

New and existing Spark customers can sign up for the One Number Wearable Plan, as long as you have a Pay Monthly or Business mobile plan. 

At this time, One Number isn't supported for prepaid and corporate accounts.

No, you'll have the same mobile number on both your Apple Watch and your iPhone with the One Number Wearable Plan from Spark. 

If you want to have separate mobile numbers for your watch and your phone, take a look at some of our other smart watches. 

Besides the devices listed on this page, we can’t confirm whether a specific phone or watch will work with One Number. 

We're continually improving and expanding our One Number capability, so we hope to add support for more devices soon. 

Currently, One Number from Spark is only available on the $7.00 One Number Wearable Plan with Apple Watch (GPS + Cellular) models. See What you'll need above to learn more. 

You can have up to two Apple Watches on your Spark account, with a few caveats: 

  • You'll need two separate $7.00 One Number Wearable Plans, one for each watch.
  • Only one watch can be worn at a time. Turn on Auto Switch in your phone's Watch app to make sure the watch you're wearing is active.
  • Both watches will share the number of your iPhone. This means you'll only get calls, messages and data on the Apple Watch that you're currently wearing. 

Both watches will share your activity and workout information to your iPhone. You can see your daily move, exercise and stand progress in the Activity app on your iPhone. It just might take a minute for all the data to sync.

You might accidentally delete your eSIM profile. This happens if you restore factory settings on your Apple Watch.

If you delete your eSIM profile, you’ll need to pair your watch again. Use the instructions above to pair your Apple Watch with your iPhone.

To delete the One Number Wearable Plan for your Apple Watch, you’ll need to call us on 123 or visit a Spark store. Find your nearest store
