Hey Rob, would it be ok to add the Huawei EM820U to the OP as officially working for CF-19 and CF-30 (pending testing on other models)? I never believed that all
WWAN modules had to be specifically made for Toughbooks, and I have proved it. I think it's mostly the Gobi modules that are restricted by firmware to certain laptop models, but most others are not. There are still some modules that won't work on our Toughbooks due to some technical reasons such as the infamous pin 20. But still, I have purchased several unlocked modules that were pulled out of other laptop brands and had them working to some degree on my Toughbooks. The EM820U is the only one I have fully tested under Windows XP, Win7, Linux and is worthy of mention. I managed to get a few others recognized under Linux but lacked SIM cards and network access to fully test them, but were recognized by the BIOS and the OS.
