GMR now offers a kiosk mode
A typical PoC handset available from GMR
As part of our successful PTT application, we now have a kiosk version. The PTT client works exactly the same as our standard version except Kiosk mode is used for times when you need to lock down a device to prevent users from installing additional apps and services. The kiosk mode also mitigates against unwanted device alteration which could cause an impact on the device and user experience.
