Works: Kyocera KPC680 on Cradlepoint MBR1000 with Mobi Hele service

This combination of hardware and service works just fine.

In the Cradle point web based administration tool, usually accessible from 192.168.0.1 go to Basic > WAN > Cellular Modem PPP Authentication (optional) and select ExpressCard then enter the information provided by Mobi for your username and password. Choose "Auto" for Authentication Protocol.

Then go to Modem > Settings > Modem Specific Settings > Access Point Name (APN) put in:

mobipcs.com

That should do it; contact me if you have any problems.
