AT&T NUMBER SYNC

Instead of using number sync, try to set up the watch in the phone with Samsung call and text on other devices. I've see a couple posts here and Reddit that say it does work now.  

Hey Skybear, 

I am having the same issue as you. phone is a s22 ultra and has the system error and the watch 4 has 200 error. 2 days for me. Several eSim switches did not provide anything. The store guy said number sync is down to wait it out. I started a question too then saw yours. 

Yeah I was thinking that it was my phone because I upgraded to this new phone and I thought maybe my phone was the problem. And ive also had multiple e sim switches and did not work either. But thank you so much for letting me know! Did they say how long to wait it out for?

Ok, thank you! I will try Samsung call and text! thanks

@kombat  please post if you get a fix. 

That's far more optimistic than previous comments or updates from atthelp

Hey @kombat 

On your S Ultra 22, does your E sim for your watch show up on your phone? On my phone, it shows my normal sim card ( for the phone) but then shows a E-sim too.. 

@formerlyknownas  

thank you! I will try that

my s22 does not show any other sim. I checked the watch 4 and the number for it has went away per the about watch section of the wearable app. I was told to not remove the "mobile plan" if it gets removed the eSim is no good. Plan is (AT&T- 1234) in the wearable mobile plan section 1234 is = to your plan ID.

USE CALL AND TEXT ON OTHER DEVICES!!! It WORKS JUST FOR TEXTING THOUGH. NOT CALLING, BUT ITS A START

@Skybear5683  my call and text doesn't see my watch 4. the s8 ultra is listed though.
