Check if Do Not Disturb or Airplane mode is switched off. Check your Apple Watch’s Control Center to confirm that both Do Not Disturb and Airplane mode are switched off on your device. If either is turned on, you won’t be able to receive messages or other notifications (by intention). Check your connection.
Why is my Apple Watch not receiving texts?
Check your iMessage settings On your iPhone, go to Settings > Messages and make sure that iMessage is turned on. Then tap Send & Receive and make sure that you’re using the same Apple ID that your Apple Watch is using. If you aren’t signed in, sign in to iMessage with your Apple ID.
Why am I not getting text notifications on my watch?
If you’re not getting notifications on your Apple Watch from a specific app, then you may have accidentally turned off alerts for the app. Find the app that you’re not receiving notifications from and tap on it. If you have custom settings setting up for the app, make sure the switch next to Show Alerts is turned on.
