ATT NumberSync not working

I'm trying to get my Samsung Galaxy S10 phone and my Galaxy Watch 5 to successfully perform NumberSync without any luck.  (Been trying for days now and have an open case with ATT Support, CM20221014_154858141).  

The phone won't display a sync code and the watch gives me an error, "SD-SDK-400".  This is a repeatable error but I can't find a resolution and ATT has not helped yet either.

I have an ID with ATT that is linked to my phone,  Any help would be appreciated since I'm paying for this service and have a LTE watch.

Are you using Samsung's 'wear' app? 

Are you signed into your Samsung account on the phone?

Yes, I have the "wear" app and yes I'm signed in.  Tried the suggestions in the link provided but still get the error message.  

Set up NumberSync from the Galaxy Wear app

  1. Open the Galaxy Wear app on your smartphone.
  2. Tap Settings and then Mobile Plans.
  3. Choose AT&T NumberSync, then Get Started.
  4. Tap Sync Watch.
  5. Check your watch for a Sync Code. this is where it fails every time!!  SD-SDK-400
  6. Enter the Sync Code in the app (if it doesn’t automatically enter it for you).

This was all done when I opened a case 5 days ago. Still am waiting on an update.
