What's the difference between the Apple Watch GPS model and GPS + Cellular model?

Apple Watch models with GPS use the network connection of your nearby iPhone to make and receive calls and texts. The built-in GPS works independently of your iPhone to map distance, pace and routes during workouts.

Apple Watch models with GPS + Cellular have an eSIM, so you can connect to the Spark mobile network. This means you don’t need to be in range of your iPhone to make or receive calls or texts, or to use data to browse the internet. 

You'll need an eligible Spark Pay Monthly or Business mobile plan, plus the new $12.99 One Number Wearable Plan. 

If I bought my Apple Watch overseas, will it work in NZ?​

Some models of overseas Apple Watches will work with Spark's network. Spark NZ supports Apple Watch Series 3, 4 and 5 with LTE bands 3, 7 and UMTS 2100 MHz and 850 MHz. Learn more about bands, supported locations and carriers at

If I already have a compatible cellular Apple Watch, can I sign up for One Number without buying a new watch?

Yes, you don't need to buy an Apple Watch 5 to use One Number from Spark. You can connect your cellular-compatible Series 3 and 4 Apple Watch with the One Number Wearable Plan. Make sure you've got the latest software on your watch and your iPhone, then get set up using the Watch app on your iPhone. Or, come see us at a Spark store. How to buy the One Number Wearable Plan from Spark

How can I cancel my One Number Wearable Plan?

You can cancel your plan the same way you would cancel a regular plan. See how to cancel a plan

Are emergency calls supported on the Apple Watch?

Yes, emergency calling will work on Apple Watch (GPS + Cellular). The watch will call using your primary mobile number.

How does international emergency calling work on the Apple Watch?

You'll need a New Zealand eSIM to be able to make international emergency calls in New Zealand. Support for SIM-less emergency calls varies by country. You don't need international calling allocation to make an international emergency call, but you won't be able to alerts contacts via text message.

If I want to connect an Apple Watch with cellular to my business account number, can I pay for the One Number Wearable Plan myself?

At this time, customers who have a business account cannot add the One Number Wearable Plan to a separate account. This is because the One Number plan is billed with the primary Pay Monthly mobile plan to which it's linked. So if your phone plan is paid for by someone other than you, we're not able to add the One Number plan to your account. We recommend reaching out to the MySpark account holder of your mobile plan to find a solution.
