A widespread scenario is where a device might get lost or broken, and you do not have physical access to the device. The best practice recommended by us is to maintain a list of Wi-Fi MAC Address or IMEI Numbers of all the activated devices. You can note down these values from SureLock and SureFox About screen. In case of a problem, you can just write back to us with the device’s Wi-Fi MAC Address or IMEI Numbers values and we’ll free up the license for you.
