I wasn't sure whether I had an Access ID or User ID so I went to the first link. The first link then text me a 4-digit code to "complete your mobile validation." After getting the text I was then suddenly worried of screwing things up badly by inadvertently creating two Access ID accounts, so I went ahead to the second link to see if I could login. I was able to login but I don't know if it was with an Access ID or a User ID. After "connecting" my iPhone with AW in order to pair it, the Watch app asked if I wanted to setup cellular. I decided to go for it . . . it worked! I'm now setup with cellular done completely through the Watch app (didn't need to call AT&T), does that mean I indeed do have an Access ID? Since I'm setup with cellular is that proof I have an Access ID and not a User ID?
