Turned out to be an extra feature on my account that someone added by mistake causing the issue, it was called NumberSync twin in their system. 

Thanks for your response, @Ryantai.

We're glad to hear that you were able to resolve your concerns. Feel free to reach back out if you require any further assistance.

I have had synching issues since purchasing my apple watch and iphone 13 pro max in late December.  Each time I am told it is fixed, it continues to not work and is not working now.  I need to have a phone and watch that will work, I am paying monthly for service and have spent hours trying to get it fixed.  My watch has been replaced although it checked out to be OK.  What is next?

Sadly our ATT cellular plan is not syncing with our Apple Watch Series 8. My husband and I have done everything for the past 48 hours and nothing works. Unpair, reset Apple Watch, Start all over again from SCRATCH! and still NOTHING - Sadly the Apple Watch Cellular settings States PLAN: NO SIM - which is WRONG! Flat out wrong the Apple Watch has an eSIM and we are paying two plan for two Apple Watches Series 8. as for STATUS: NO CONNECTION - makes sense because according to the Apple Watch there is NO SIM. ATT fix the issues with the eSIM and Apple Watch. I have chatted with reps who all state it is connected. I have phoned multiple reps who keep having me take the steps: unpair, reset, start at the beginning. The definition of INSANITY is doing the same thing over and over expecting a different result. Well this is insane. Fix the issue with Apple Watches for the LOVE OF GOD - fix it. The Apple Watch is not NEW there is no excuse for this lackadaisical attitude towards clients. I will happily return both Apple Watches and 5 watch bands back to Apple Store Tysons VA Monday. GET'er DONE!

Hi I’m currently going through the same thing I’ve chatted with support for hours straight they either end the chat or redirect me to calling the AT&T fraud department for some reason. I have yet to find a solution but will post one if found 

Same here. It has been 48 hours still no action. It is the strangest thing. At least yours hung up or disconnected the call. Mine would tell me "did you really unpair the watch?" and other silly questions. Today I went to our local ATT store and the gent did the exact steps I did multiple times Saturday with the same results: Oops! That's not supposed to happen Give us a minute and we'll get it fixed so you can try again. (EDS4014)." He has set up 20 Apple Watches Series 8 and our two Apple Watches 8 are the first troubled ones he has encountered. I took multiple screen shots to prove my case. The Apple Store Tysons VA promised me set up is easy. Ha! joke is on Apple Store Tyson VA employee. I will update, but sadly I suspect I will have to transfer our account to another carrier.  So long ATT.... 

Update: ATT never activated the EID for our two Apple Watches Series 8. Now why that didn't occur when I took EVERY set up new device steps for the Apple Watch is beyond me. Why ATT website for current clients NEVER activated our two EID is beyond me. But it works. Asanchez360 maybe this will help with activating your watch with your cellular plan. 🤞 keep me posted 😁 Cheers

The fix for me was that I had cellular data turned off on my phone for some reason.   In your iphone go to settings and make sure cellular data is turned on and then try again through the watch app.  Doh.  

Went into Att Saturday and wasted 4 hours to no avail. The Carrier Plan could not be added. To make this short, I had an iWatch 5 and bought an iWatch 8. Followed the steps at the Apple Store per reps instructions and the carrier/cellular couldn’t be added. There was a non stop error of:

“Connection Failed

The connection to the server was lost. Please try again later.“

Here is the solution for me: 
1. Went into my iPhone Settings

2. Click Cellular 

3. Swipe off (turn off) Cellular 

4. Wait about 30-45 seconds

5. Turn Cellular back on

6. Go to iWatch app select “Set up cellular”

7. Number sync will show and verification of 911 address:

“Let's set up NumberSync§M

Emergency 911 address

Enter your emergency 911 address so you can sync your watch and use AT&T cellular service.”

The number sync is for the purposes of 911 and your home address in case of an emergency.
