Same here, I cancelled my cellular plan on my watch due to I barely use it. I have serial 3. In order to use the cool feature over Siri on watch, I guess I have to have my watch syncs with my phone while use that feature. Or to get cellular plan back, so that’s like $10+ per month and Plus $20 app for the James Bond feature, still cool thoughBefore plunking down $19.95 for the app, I'd love to know this, as well. I have an Apple Watch with cellular but just changed providers and the new provider doesn't support Apple Watch so I'm only tethered to my phone via BT now.
