I received my Watch 3 on September 22 and, of November 15, still have not been able to receive calls on cellular with it. I have been in constant communications with both Apple and AT&T to resolve the problem; but nothing has happened. I have spent at least 30 hours (that's right: 30) with an Apple senior advisor in search of a solution. Basically, when someone calls me, the Watch gives no indication of the call; although if I search my missed calls on the Watch, the call shows up. Unfortunately, I only learn of the call after the fact. When it's coming in, I don't know about it. It will sometimes show calls if it's right next to the iPhone; and I can actually call out on cellular. I've reinstalled the software several times. I have done data dumps from the Watch that have been sent to Apple's engineers; but still no answer. And I can't get a reading on when this will be resolved. I asked for a new Watch; but Apple says it's not a hardware problem. Has anyone else had a similar problem? If so, has it been resolved and how? Thanks.
