Hello, Bbyaby. Thank you for taking the time to share your feedback about your new Apple Watch Series 11. Because an Apple Watch relies on synchronized network settings to handle cellular data and notifications properly, we recommend trying a few troubleshooting steps to get everything aligned: -Ensure that NumberSync is fully activated in your account settings so your watch can share your iPhone number for cellular data. -Turn both your iPhone and your Apple Watch off and back on again to refresh their connection to our network. -Check for any pending carrier or software updates on your paired iPhone by going to your general settings. -Confirm that your notification settings in the Apple Watch app on your phone are set to mirror your iPhone alerts. If your watch still will not connect to your cellular plan or continue to delay notifications, please send us a direct message on your preferred social media channel so we can look into your account and eSIM profile details.
