Getting No Service message on your Apple Watch despite having an active cellular plan? The cellular plan automatically links with the Apple Watch when you pair it up with your iPhone. Now, the Apple Watch only shows up the ‘No Service’ message if it can’t get any cellular services. This may happen due to any of the reasons such as corrupted cellular plan, a glitch in the watchOS, etc. Go through these solutions to retrieve the active service.
Fix 1 – Refresh the Airplane Mode

Step 1 – Slide down from the top to load up the Control Center of the Apple Watch. Turn on the Airplane mode from there.
Step 2 – Wait for 10–15 seconds. Then, turn off the Airplane mode from the same Control Center.
Check the Apple Watch for an active cellular connection status.
Fix 2 – Force Restart the Apple Watch and iPhone
