Modifying iOS settings to manage roaming status does not apply a permanent restriction. End users are able to make changes to these settings manually if needed.
To override default settings in order to modify roaming permissions for an individual iOS device.
- Navigate to Devices > List View. Filter by Platform to locate your desired device. Select its Friendly Name to launch the Device Control Panel.
Select More > Managed Settings.
Select the Enable or Disable radio button to override current Voice Roaming Allowed, Data Roaming Allowed, and Personal Hotspot Allowed settings.
- Click Save.
