Apple Watch cellular set up
Hi - I have Apple Watch 9 supporting cellular+gps, and iPhone 11. My mobile account is with Three. I am trying to set up the watch to use cellular. The Apple User Guide says open the Apple Watch App, select My Watch, and then choose the Cellular option. However for some reason I don't have a Cellular option. Why do I do to resolve this?
Apple Watch Series 9, watchOS 10
