Intune iOS Devices - FAQ
What to do if a device that is in Kiosk mode is unable to connect to the internet.
There is a PBR Wi-Fi Policy enabled in Intune that enables automatic connection to PBR Wi-Fi (Internet). If for some reason this Wi-Fi becomes unavailable whilst the device is in Kiosk mode then it is not possible to take the device out of Kiosk mode due to the fact the device needs to be connected to the internet to enable changes made in Intune to sync to the device.
A simple solution is to setup a hotspot from another phone, make the SSID internet and specify the same password as for the PBR internet wifi .. then the device should be able to connect and changes in Intune can then be sync'd to the device
