Apple Watch Ultra 3 Cellular issues on AT&T

Replaced older AW 8 with AW Ultra 3. AT&T network. Watch won't connect to cellular no matter what. Spent over 2 hours with ATT support (including advanced tier 2) and they can't do anything.

Tried:
- unpairing/re-pairing
- erasing/rebooting
- removing plan from AT&T, adding new one
- resetting network settings on phone
- swapped Ultra watch for a new pair (thought original was faulty)
- confirmed EMIE/EID numbers, ATT reps tried pushing new eSIM at least 5 times, but it won't get to phone.

When I go to cellular in my Apple Watch App, it shows "AT&T" plan, but it's "Not in use". Can go through adding cellular plan again, it confirms "NumberSync is now enabled", but going back and seeing the same thing. Watch shows "No SIM, No Connection"

Wondering if anybody else is having issues with their AW Ultra 3 on AT&T network (or any other one)?

My old AW 8 worked on cellular just fine, no issues at all. Love the ultra otherwise, but would likely have to return and go back to my old one... so annoying.

Yeah, I'm at a point where I'm not sure if it's better to return AW Ultra (which I like otherwise), or jump to another provider and forget the AT&T nonsense...

I have spoken with AT&T multiple times and can confirm that there is an issue with their 5G network and Apple Series 11 and Ultra 3 watches which they are working on now. I was told they will send me an update when the matter is resolved. Prior to this, I tried every troubleshooting method, including watch replacement. I had a Series 11 and then switched to the Ultra 3. Both had issues connecting. The senior techs also attempted to reprovision the NumberSync which did not work either. Definitely AT&T issue. They have agreed to refund my mobility fee fees for the month until they’ve resolved.

AT&T service is spotty at best here in So Calif but I use it for my mobile data hotspot service for my EV car.

As for great cellular and AW reception, I use Verizon.

Any updates. Having same issue activating cellular on Ultra3 with no resolution from Apple or AT&T since launch in September.
 
I ended up dumping AT&T and went back to Verizon - zero issues, much better reception, although roughly 20% more expensive.

Yes, they seem to have resolved the issue, but it required updating the mobility plan. The new plan includes 5G networks.

I had updated to the AT&T Wearable Unlimited Plan, but that didn't resolve my issue. I was on the phone with AT&T for over 3 hours again last night until my call dropped without a fix. During activation process I can not get past NumberSync process before getting kicked out of activation process. NumberSync successfully activates but process starts over again on watch App to set up cellular and AT&T Not IN USE. On AT&T side they show everything is active, but eSIM does not get loaded onto my watch and watch showing NO PLAN and NO CONNECTION. Apple did a lot of diagnostics on the phone and watch and were unable to find anything wrong, blaming AT&T. I just decided to cancel my cellular service. I am frustrated how difficult it is to escalate anything with AT&T. 40+ hours trying to resolve and needing to start over every time I contact AT&T. They are not reviewing any recorded conversations or history to help. It seems like an unknown issue to them. Each AT&T agent says they will stay with me until they resolve, but give up in the end saying everything looks good on their end. Not clear what is providing AT&T with that false information, since it is obviously not working.
 
Sorry to hear but understandable why you changed carriers. The plan I signed up for had been released the day I called so it's very new and some of the the support didn't even know about it. This is a real mess for them so I hope you have better luck elsewhere.
