I am aware it needs it’s own number. Just frustrating their automated systems are broken (in my case). Their site is not accepting my credentials to login, and, on the call, they are asking for a lot of information that is irrelevant to the process. Now just having been asked for my DL# to confirm Credit..It does have it's own phone number. NumberSync for Apple Watch (Cellular) does the magic and it needs to be setup. The setup of NumberSync is part of the initial setup or "on watch" setup or can be done manually in Myatt.

Then just now, after 35 minutes, I was transferred to someone else, without warning, and the individual did not hand off ANY of my information. I am now starting over, from scratch, reading off numbers from my box to get this device activated.
