I replaced my cellular AW 4 to a new 7. Didn't think to test making calls and now I realize if the phone isn't on, the watch won't make calls. I re-paired, re-paired as new and Apple sent me to T-M. Their help is saying to repair as new, and first tried "keep cellular plan" and didn't work, next had me set up as new cellular plan. No luck. Is this something on their end and I'm not getting to the right help?
