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.
