Thank you for your interest in a Franklin Access product! The insert card that comes with the T-Mobile RG2100/RG3100 refers to an offer for a free trial of the JEXtream MDM (Mobile Device Management) service. This is basically a tool to be able to manage the hotspot settings remotely instead of logging onto the hotspot web user interface (http://mobile.hotspot) to access your hotspot settings.

The key difference between MDM and the hotspot web UI is that with MDM, you can access your hotspot settings remotely. But with the hotspot web UI, the hotspot must be connected to the device you are using to even be able to access it. Both methods are tools to use in managing the hotspot settings, so it depends on your personal preference on which you would rather use.
