AT&T numbersync nightmare

To solve this problem took 6 days and much persistence. Somehow when I tried to set the watch up for the first time there was an issue where instead of making the watch connect to the account properly it was registered as "parked equipment." Numbersync set up and came up with a number for the watch but somehow it wasn't making that final step and I kept getting the same error messages on my phone as discussed above. The problem was that as has been mentioned above I needed to get to "Advance Tech Support" and had to convince AT& T reps to get me there. My solution was calling on a Sunday right when Pro Tech Support opened (10:00 am eastern). In under an hour my phone and watch were communicating without me having to unpair and pair the phone and watch again. I did have to shut both devices down and then once Advance Tech Support saw the existing Numbersync number it went quickly. Hope something in my reply here can help others with issues.

Same issue here, I think. On with AT&T for the third time now. I've also been monitoring this thread at MacForums--seems to be a relatively widespread issue.

To confirm, it seemed to set up with no issue--got all the way to the NumberSync section--but now in the Apple Watch app's cellular settings it says "Set Up Cellular," and when clicked, ends with an error screen saying "Hmmm....something's not right. To sync this device, ask the person who manages your account to call us at 800.331.0500. (EDS4007)"

On the watch, under cellular settings, it says "Plan No SIM" and "Status No Connection."

Seems to be a NumberSync issue on AT&T's end, but who knows. They don't seem to have a clue.

I just bought an Apple Watch series 3 cellular and have the same EDS4007 issue. AT&T is clueless about this. It’s been 3 days of constant calls to the customer care and frequent trips to the AT&T store. They keep asking me to unpair and pair my Apple Watch.

The sync process while pairing the Watch is completely messed up. It makes you sign in to your AT&T account and requests a new number to be reserved for the number sync. Since I did the unpair and pair thrice according to AT&T’s customer service instructions, I got 3 numbers reserved from AT&T and none of them worked. AT&T emailed me saying that all number sync activation requests were denied. So I finally went to the AT&T Store. Those guys are even more clueless than AT&T’s phone based customer care representatives. They kept telling me that my watch’s serial number was associated with another account since they couldn’t see the 3 numbers that were reserved. They also told me that the watch was bad and I need to return it. I pressed them on and then they told me that the store guys don’t have the same level of access to our accounts as the representatives that respond on customer care over phone. Finally, the AT&T store guy called up AT&T customer care and was told that 3 numbers were reserved. He cleared that up and activated one of the reserved numbers but then I started getting this EDS4007 issue.

AT&T has generated a problem ticket for this and said that they will get back to me in 24 hours.

Numbersync on Apple Watch is totally messed up and the process is not well established. My advice to anyone reading this is to wait out a couple of months before buying the cellular version of the Apple Watch. It might be that AT&T doesn’t know how to do this. Other carriers might be ok but I don’t have statistics about them.

Thanks for replying.

How do I do the pin verification? I hit the EDS4007 error when I go to the Apple Watch app on my iPhone and click on cellular menu followed by “Set up cellular”.

In the meanwhile, I will try to call AT&T customer care, ask for advanced tech support and mention the pin verification. Let’s see how this goes.

I've been fighting this for 3 days now. Literally hours on the phone with tech support to no avail so far. I'm so **** frustrated with this phone/watch, I am beside myself. Good luck with the number sync folks.
