Apple Watch does not ring when my phone is off

2 Apple Watches paired to 2 iPhones (different) and if the phone is off we get dead air/call failed. Spent hours w/ Apple & Xfinity Mobile (Tier 2). Tried to unpair/pair watch/phone. Deactivated mobile plan etc. Nothing is working.  When my phone is on and watch connected to it my watch ICCID shows 'no sim'.  If I turn my phone off and wifi off on my phone the ICCID will populate with a number.  That number matches what XM support is expecting so the watch is 'provisioned' correctly.  It sounds like this is a problem with your network, not my account. Also have a co-worker who assumed everything was working correctly, but was able to reproduce the problem with his devices as well.

I have 3 ticket numbers.  Each time I call your support number they say they can't find any of the tickets and I have to create a new one. 

Can anyone assist?

First things first. It sounds like your cellular settings and provisioning are correct. On your Watch you should see one of the three Network settings:

1.) Not Available - When connected through your iPhone nearby. 
2.) XM WiFi - When not connected through your iPhone, but using recent WiFi connection used by both devices and your Watch is using WiFi Calling. 
3.) Xfinity Mobile - When connected through eSIM on watch to cellular tower. 

Most likely your Apple Watch settings need to be corrected. See the following Apple discussion:
