Sprint user how to set up cellular

Hi Stacy Nachman,

Thanks for using Apple Support Communities. We understand you having some questions about setting up cellular data on your Apple Watch. We're happy to provide some information to help.

We recommend checking out the information for setting up cellular data here: Set up cellular on Apple Watch

If you run into any issues with those steps, reach out to Sprint for further support.

Thanks

You cannot use a SIM for the Watch. The Apple Watch uses an eSIM and it is already installed in the Watch. You can activate your Watch cellular from the Watch app on your iPhone. You need information from your carrier, Sprint.
