First - is your card Lenovo branded? Does it have a Lenovo PN FRU on it? On T series (at least) one cannot install a generic wlan/wwan card without a third-party modified BIOS (for whitelisting) - and I think there is no such BIOS for T420s.
Second - as far as I know - hope I'm not wrong - on T420s you have only two WWAN options: Qualcomm Gobi 3000 (PN 0A36185) and ERICSSON F5521GW (FRU PN 60Y3255).

Yes the card has a FRU (60Y3237) and i'm using a modified bios, it should normally work.
The card is properly installed and detected by the pc, but he keeps unpluggin and repluggin it, i don't know why!

Thank you.

I have similar issues, 3G modem disappearing from Device Manager without reason. The card is F5521GW, the card it self has been changed to a newer rev and the whole motherboard was changed too and Windows 7 x64 was reinstalled too. Latest drivers for everything and still this is ongoing problem..for over a year. I think this is a bug in the whole system and can't do much anymore when everything is changed. I only think if Gobi 3000 would work, that's the only other one (according to lenovo support phone) that should work with T420s.
