Lost watch
I lost my watch. How do I turn off the cell phone service to it? Do I have to call ATT or can I do it myself? It takes an hour to get through to them.

"Contact your wireless carrier

report your missing device to your wireless carrier.
Ask the carrier to disable your account to prevent calls, texts, and data use.
And if your device is covered under your wireless carrier plan, file a claim."
