Galaxy Watch 4 Classic NumberSync not working

I think there may be a bug with the Galaxy Wear app or the GalaxyWatch plugin with respect to AT&T number sync. I've spent more than 11 hours with AT&T trying to fix this issue and can't seem to get it resolved.

When you try to NumberSync, it should open up a web page or the AT&T application for you to sign in. But it doesn't. All I get is a NullPointerException or JsonSyntaxException error code like below.

The watch software is up to date. The Galaxy Wear app is up to date. The watch has been provisioned three different times now. The watch is active by itself, but NumberSync just won't work. I've even done a factory reset on the watch.

It seems like there's a problem with the Galaxy Wear app code where it is trying to complete the NumberSync but it can't find the app so I can log into AT&T. Maybe the script is broken?  Anyone else have this issue? My next step is to swap out the watch and go through this again from scratch.

Samsung's update yesterday 2/8/2022 appears to have fixed the issue. My watch is now synced with my phone. If anyone is still having issues, try updating your phone and then restarting both devices. Hopefully the issue has been completely resolved.

I’m having the same issue too. It started a couple of days ago. I didn’t update anything, neither the watch, nor the phone, nor the app. AT&T is unhelpful. Prior to this it was working fine. Very frustrating.

I just got the watch 1 week ago and I am having the same problem. Watch screen says sim not provisioned, error with number sync. Was told it would work with the note 9. Looks like I may have to up grade to a newer galaxy phone......

Might want to wait until Samsung fixes the issue before you upgrade. I've got a Galaxy Watch 4 and a Note20 Ultra so I don't know if upgrading will fix your issue.

Guess what! I'm here with the same issue. S21 ultra and galaxy watch 4. ATT reps don't have a clue on what to do or how to fix it. I've been seeing online that this is becoming a pretty big problem so it should get fixed soon.

I am having the same issue; been almost 3 weeks now. Was working perfectly and then it wasn't. Spent far too long on with AT&T Advanced Tech Support and all they can tell me is that it's being worked on. Watch 4 app updated software today and Wear app updated yesterday, still no go for me.

Watch app plugin failing several times a day. I dont expect samsung to really do anything about this,for I've had issues with several devices that i have spent mega bucks for. Samsung has been silent. I wonder how customer care is over on the Apple Platforms?
