You can connect your cellular Series 3 and 4 Apple Watch with the One Number Wearable Plan, as long as it is compatible with our network. 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.

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.
