tammylafram, I'm sorry to hear your daughter's smartwatch was stolen. I'll be happy to share how to suspend the line the watch is on, and then where you can go to file an insurance claim.
To suspend the line, you'll be able to do that in My Verizon. In the Suspend Service FAQ page, there is a section on Lost/Stolen Suspensions. Question #2 outlines how you can suspend the smartwatch line through the My VZ app and online in My Verizon: https://www.verizonwireless.com/support/suspend-service-faqs/
Once you've suspended the line, you can then reach out to our Asurion partners, to process the insurance claim. You'll be able to file a claim for the watch online: https://www.phoneclaim.com/verizon/
I'm glad I could get that information. Let me know if you've got any further questions.
