At times, restarting your phone and Samsung Galaxy Watch is enough to fix the notification issues. To restart your Watch, you will need to turn it off. ... Once the device turns off, press and hold the Power button again till the Samsung logo appears. Then release the Power button to turn it on.
In the Samsung Wearable app on your phone, tap Watch Settings > Notifications > More, and make sure that the Phone toggle is on. If that toggle is off, you won't be able to answer calls on your watch. ... Try Connect to that, and see if calls work
Thanks for your help but tried that too has been working fine until xmas eve when you try to make a call it says emergency calls only then ends call but i can send a text using my phones number while phone is home
