I've clipped the UK specific info from those linked threads. I think you need the Canada drivers linked at the bottom of this post.
The above comments are correct if you are in the US; if you are in Europe/Canada or other "unlocked" places then you only need the Gobi drivers and not the CSA.
I've read this and the advice is to install a CSA software, but that is not needed as i'm in the UK?
In which case there are differences between Europe and the US. In Europe:
CF-19mk1 had Novatel EU740
CF-19mk2 had Novatel EU870D
CF-19mk3 had Qualcomm Gobi 1000
CF-19mk4 will have Qualcomm Gobi 2000
In Europe there are no field upgrade kits, you stick with what you've got. But then over here, we don't have CDMA or EDGE networks, everything is GPRS or 3G (UMTS/HSDPA), so there's not as much need for upgrading.https://panasonic.ca/PCS/Software/Tough ...
