apple watch series 3 lte siri connection problem
My new Apple Watch works great when connected to my iPhone using both Wifi and cellular connections. But in standalone LTE mode (i.e. watch not connected to phone nor to WiFi) the watch can only makes or initiate phone calls. Siri, text/iMessages, emails or any phone apps using data don’t work. In particular, Siri responds with "No Siri connection". Does Siri require phone connection?
I’ve searched through the settings and can’t find anything to enable cellular data for the appls. The Cellular tab of Apple Watch App on the iPhone shows 341 KB of data used for “System Services” but nothing for the different apps.
Specifics:
• Apple iPhone 7 with iOS 11.1.1
• Apple watch 3 (LTE) with watch OS 4.1
• ATT (business account) and all carrier settings up to date
Have tried following at Apple Genius Bar:
1. Unpaired and repaired (including backup) – no improvement
2. Unpaired and reset/set up as new – no improvement
3. Ran hardware diagnostics -- watch passed all the tests
Thanks for your help
