I have just got a T420 (Win 7 64bit) which did not have a 3g module. I took the gobi 2000 out of my t410i and put it in this machine. I have installed the driver for the t410 and it installs perfectly, although it does not list the T420 as a compatible machine.
I can create the dialup with the gobi modem but I keep getting an error 619 and it will not connect.
I have tried installing access connections and connecting via mobile broadband but still no luck. If I go to in access connection to advanced, tools, mobile broadband (which is now no longer greyed out) I can see existing SMSs on the sim card but send or receive new SMS so it seems the card is not registered on the mobile network.
If I press FN+F5, WWAN is not listed so I can’t turn it on.

The Gobi card version changed from the T410 to the T420. The T410 user the Gobi 2000 card while the T420 uses the Gobi 3000. In my experience they are not interoperable between the different models. You can install the drivers for the 2000 on the T420 but it won't recognize the card and often times when you reboot you'll get a black screen with a message that an unauthorized device is installed. Sorry to be the bearer of bad news but your T420 will need a new WWAN chip.

Not going to work folks. The T420 uses GOBI 3000 not the GOBI 2000. You would need to purchase a GOBI 3000 card (Part Number 0A36185) or outside the US, you can use the Ericsson 5521gw card (0A36186). You would need the GOBI 3000 card to connect to Sprint or Verizon in the US. Other SIM based providers can use either card.
