Good evening, 

I was curious if numbersync will always be a perpetual problem child. Galaxy watch 4 to note 9. Initial integration problems, then on and off functionality for 3 years. More unsolicited disconnects, factory reset. Multiple e sim tries. Current error code 146.

If numbersync does not work reliably, then there is really no reason for a data plan on the device. 

Will a mobile radio equipped watch contact 911 in the event of an emergency with no data plan?

We understand your frustration with Galaxy Watch 4 having syncing issues, SuperiorAg.


Make sure you have the most recent software for your wearable and the Samsung Galaxy Wear app on your smartphone to ensure you have the latest features and device protection options.

  1. Go to Device Support.
  2. Choose or change the device brand and model.
  3. Select Device diagram.
  4. Scroll to More Device Help and select Software updates if it’s there. You’ll only see it if there’s an update for the selected device.

Fix failed updates

Sometimes your device may have trouble updating. Here are some common reasons and fixes.

Memory issues

Each update requires a certain amount of data.
  • You may have to remove apps or data to increase your device’s available memory.
  • You can back up your data before deleting it.

Our next recommendation would be to use this resource to resolve NumberSync issues


Uncertain whether you have an AT&T Access ID
If you aren’t sure if you already have an ID or need to create one to sync your wearable to your smartphone, visit AT&T Access ID for NumberSync for wearables.

Manage your AT&T Access ID
To learn more about managing your Access ID, visit Manage the wireless number for your AT&T Access ID.


We also suggest that you view this helpful forums thread on syncing your Galaxy Watch 4


When a cell site experiences interruption, any 911 call will automatically connect to any available network, regardless of your carrier, to complete the emergency call. You can also enable Wi-Fi calling on your phone if you have internet access. You can also text 911 by using the numbers 9-1-1.


You can also place your Smart watch on SOS with this resource.


Please let us know if this helps. Thanks again for reaching out to AT&T Community Forums!
