Numbersync issues with Galaxy Watch

I very much have a similar issue as you. I bought the 42 mm galaxy watch on Friday last week and went through multiple tech support calls and we can not get numbersync to work. I also spoke with a chat support manager that told me he's not really sure why ATT is selling these right now because in their system none of the new galaxy watches are showing as being compatible with numbersync yet. It's not even listed on their compatible device page for numbersync yet. See below

I saw some other threads where people got it to work by scanning the QR code on the blue esim cards you get from the store but I did that multiple times and it goes through but then when the watch restarts and I try to setup numbersync I either get "SIM not provisioned MM#2"  or I get "Numbersync is unavailable" I called support again and they told me they see the line activated on their network with a phone number but until numbersync is working it will not work. 

I can make calls from my watch and it shows that my number is my phone's number. I used the QR code from the card. It just seems like there is something wrong with numbersync. It just keeps randomly disconnecting and when i connect again it tries to sync all those messages from my phone which is killing my battery

Your not on prepaid are you?

Nope. I have a note 8 which I bought from the ATT store and the galaxy watch which was bought from the same store. The day I picked up the watch they weren't able to activate it because of a problem with their system. So I called support and they were able to activate the watch but they told me nubersync wouldn't work until I got the blue card and scanned it in the samsung app. So I did that didn't get any errors but no matter what I do it will not generate the sync code for number sync. It just gives the errors I mentioned previously.

Sounds like you have a miss matched sim card to me.  The blue card is a sim card and if they activated the esim in the phone they did cause a issue if they did it wrong.

Do you mean if they activated the esim in the watch as opposed to the esim number on the card?

I am not on a prepaid plan. i used the blue card that had the QR code on it to activate but then someone from att had to do it on their end. Wonder if they screwed it up. It hasnt disconnected in a couple hours but i have a feeling that it might. I guess i will just keep an eye on it

I think the problem may be fixed now. I havent disconnected from numbersync in about 6 hours. Support for this is next to nothing. All they told me is that everything looked good on their end. Hopefully it is really fixed. I hate having to walk around with my phone with me 24/7 since im on call. makes it a lot easier 

Update: After my 5th attempt with chat support they were finally able to fix my device. Turns out the ICCID (essentially the sim number on the blue card they use for activation) was showing as incorrect and invalid in their system. They told me apparently whenever one of the other support specialists was trying to re-provision the watch they somehow entered the wrong ICCID information. How none of the other support specialists caught this when they were reviewing my account I'll never know but everything is finally working.
