How to activate alarm notifications on a smartphone^◊,¤

To receive optional glucose alarms on your smartphone, you need to make sure you have notifications enabled for the app. If you didn't enable all notifications and permissions during app set up, how you do it now depends on your phone's operating system.

Open Settings on your iPhone.
Go to notifications and select the LibreLink app.
Enable Allow notifications.
Tap to highlight the Lock Screen, Notification Centre, and Banners options to enable all notifications.

If you use Do Not Disturb mode on your phone:
