About APNs

You must use the APNs to manage iOS devices in BlackBerry Enterprise Service 10 domains. The Universal Device Service requires the APNs to manage iOS devices and send push notifications to iOS devices. When the Universal Device Service needs to send information to an iOS device, it sends a notification to the APNs. The APNs authenticates the Universal Device Service server and then sends the notification to the iOS device. The iOS device receives the notification from the APNs and retrieves the information from the Universal Device Service.

To use APNs, your organization must obtain an APNs certificate for each Universal Device Service deployment. For example, if your organization includes a production deployment and a testing deployment, you need two APNs certificates.

You must obtain the APNs certificate through the Universal Device Service interface.

When you renew the APNs certificate, you must use the same Apple ID that you used when the certificate was created.

The Google Chrome browser and Safari browser provide optimal support for displaying functionality.

CAUTION:
You must renew the APNs certificate before it expires (each certificate expires after one year). If the certificate expires, or if you insert a new APNs certificate instead of renewing the old one, iOS devices do not receive commands, and users must reactivate their devices.
