Status icons and symbols on Apple Watch - Apple Support -- Before trying to make your next call from your Apple Watch, open the Control Center on your Apple Watch and confirm it’s connected to a cellular network. Also note how many bars are available. If it has a strong signal and you’re still not able to place a call, please contact your carrier to make sure the account has been provisioned for calling.
Also, as an isolation step, are you able to place a Wi-Fi call from your Apple Watch? Which model of Apple Watch are you using, and which watchOS is it currently on? Please provide this same information regarding your paired iPhone as well.
Take care.
