Can't remove configuration profile installed from http://altel.kz/mconfig
When i go to "Settings > General > Profile > Altel internet" there's no DELETE button.
How can i remove that profile?
The profile's removal setting is set to ‘Never’, so the profile cannot be removed by the user from settings once installed.
If you have a backup of your device made before you installed the profile, you can restore the backup. Profiles are restored from a backup so if you make a backup now that will be no use.
You may be able to use Apple Configurator to remove the profile (available on the Mac App Store). Connect your device over USB and open the device in Configurator, then go to Actions → Remove → Profiles… and select the profile to remove.
