Open MOBILECONFIG File
The MOBILECONFIG format file is a system-typed file that stores configuration data saved in XML format used by devices using iOS.
MOBILECONFIG stores information about email, passwords, calendar, permissions, proxy and VPN settings.
The MOBILECONFIG files are also used to implement and register massive installations of configurations of Apple devices within the corporate and school networks.
Therefore, these are normally hosted in a remote profile service, which communicates with the Apple device to configure and register it.
When transmitted, MOBILECONFIG files can be digitally signed so that information is sent securely over the network.
Thus, mobile configuration files can be used to automatically manage and implement configurations on a large number of devices owned by a corporation.
MOBILECONFIG files can also be created with the iPhone Configuration Utility, which is available for Mac and Windows platforms.
You can open MOBILECONFIG files with Apple Configurator 2 for macOS.
