When you download a configuration profile from a website or an email message in iOS 12.2 or later, including profiles to enroll in Mobile Device Management, you need to go to the Settings app to install it.
Install a profile
After you download a profile,* you’ll see the message "Profile Downloaded". To install the profile, follow these steps:
- Open the Settings app.
- Tap Profile Downloaded.
- Tap Install in the upper-right corner, then follow the onscreen instructions.
* You can have only one profile ready to install at a time. For example, if you download a profile and don't install it, and then download a second profile, only the second profile is available to be installed. If a profile is not installed within 8 minutes of downloading it, it is automatically deleted.
About profiles installed by Mobile Device Management
If you're a system administrator, you can install profiles without any interaction from the user on devices enrolled in Mobile Device Management (MDM). To enroll a device in MDM, use Apple School Manager or Apple Business Manager, or manually install an enrollment profile.
