I have been in two AT&T stores and the reps said they see this issue all the time. They don't have this issue with the iWatch. To me, that sounds like an AT&T issue. The last store could not get the watch set up. I guess I will have to either give out the watch's unique phone number or just cancel that line.
Did everyone just give up or did someone find a resolution that I haven't found? I've tried EVERYTHING. Funny that AT&T is pointing the finger at Samsung. I don't see any other carriers mentioned in any forms pertaining to this.
YOU SIR ARE A GOD AMONG MEN!!!!!!!! I have been racking my brain over this forever. I did have to google the steps on how to do it, but I found that and it worked like a charm. Here are the steps and info to fill in https://www.att.com/support/article/wireless/KM1062162/Samsung/SamsungSMN986U
I just spent 2 hours at the AT&T store trying to get my daughter's Active 2 LTE number synced to her S9+. After many conversations with AT&T techs, Samsung told the AT&T people helping us that it is a software issue and top priority. They have to do an update. My daughter can use hers with the bluetooth option when they are close together and they gave the watch another number on case she wants to use separate. We will sync when update released.....
I have the exact same problem.
Bought it at Best Buy.
Neither Best Buey nor At&t can get the numbersync to quit turning off all the time.
When numbersync is on it works just fine.
But numbersync keeps turning off automatically and randomly.
I have to manually turn it back on every day.

I have been having this same exact issue, I have the s10 and active watch. After talking to 8 different ATT reps and Samsung the issue has not been resolved. Exchanging the watch but I'm almost certain this won't fix it. Is this a Samsung issue or ATT issue. Extremely frustrating. I've been a loyal Samsung consumer for a long time, maybe time to switch.
i have spent many hours in the forums in addition to the hours spent with AT&T tech support and I have come to the conclusion that we are just out of luck. Time to switch.
This must be a Galaxy Watch problem. Because I did not have any issues setting up my Gear S3. They are sending me a new eSim card. But after seeing everything on the internet. I'm not confident.
UPDATE, I am posting this everywhere because I don't think the carriers or Samsung knows what's wrong
The latest update I got to my Active2 that also broke my Watch3 set the ATT APN to 'nextgenphone' which does not seem to be working yet. I created a new APN 'Phone' like it used to have and the LTE data started again.
