Someone else posted the exact same problem, this was the fix that helped them.
- Turn off the Bluetooth on your Phone/Device the watch is connected to. - Wait till the Galaxy Watch connects to the 4G LTE services. - Go to the ANNOYING notification and click on it. - Call your voicemail from the option in the notification. (even if you don't have a voicemail in your inbox STILL DO THIS!!!) - Listen to the female voicemail in the voicemail. - THIS NEXT STEP IS THE MOST IMPORTANT PART OF THIS AND IS THE WAY TO CLEAR IT!!!! - Open up the Keypad on the Watch and Press ** (Let her say "Thank you for calling, Goodbye) and the watch will disconnect from the voicemail on it's own. - Turn the Bluetooth back on the phone/device and let the Galaxy Watch connect by itself. - PROBLEM SOLVED!!!!
