Cannot add cellular plan to Apple Watch 7 via Apple Watch App
Wondering if anyone has come across this issue. I added a cellular plan to my account for my Apple Watch 7. From the Apple Watch App on my iPhone XS Max, I receive the following message when I try to Set Up Cellular. "Oops!, That wasn't supposed to happen. Give us a minute and we'll get it fixed do you can try again (EDS0243). I cannot get past this screen.
I've already spent several hours on the phone with AT&T support and they cannot seem to resolve this. I went to an AT&T store as well and they were not able to resolve.
We've done the following several times but nothing is working.
1) Verified that the correct IMEI and EID number is on the account.
2) Reset the watch several times and re paired it with the phone.
3) Deleted the Apple Watch App from the phone and reinstalled it.
Has anyone come across this before?
