This procedure will vary depending on the MDM product. On the Apple iOS device: 1. Open the Settings app. 2. Tap "General". 3. Tap "About" and view the installed version of iOS. 4. Go back to the "General" screen. Also, tap "Software Update" and verify the following message is shown on the screen: "Your software is up to date."
