iWatch 7 receive calls on watch when iPhone is off or not available?

@dwill05 The watch will make calls with your number when not connected to the phone.

Did you add a 10 dollar a month watch plan to your att account?  You have to set up numbersync..

So what is the answer to the question.  

no clue, this is a customer forum not at&t support you may get a response from a forum expert but you may be better off contacting apple

Contact Apple. It's their product.

ATT is my mobile service and the iWatch is asking me to log in with my ATT account.

The iPhone is registered with AT&T,

Doesn't make any difference. Call Apple. It could be that the cellular (freebird) version of the AppleWatch needs to be in close proximity of the iPhone, otherwise it will need to log into AT&T each time if you are using it when the iPhone is out of range or off.

I don’t believe you can make or receive phone calls on an Apple Watch unless you’re connected to Wifi or using FaceTime.  The SIM in an Apple Watch so equipped is for data only and won’t work for making phone calls over the cellular network like a cell phone.  It needs to be connected to a cell phone to be used for normal calling.
