Hi everyone,

i'm waiting for my new T400 - should arrive in ~2 weeks.
And tomorrow i`ll get a new SL500 (with integrated WWAN) for my girlfriends parents.
They really don't need the integrated WWAN. So my question is: Is it possible to take the wwan out of the SL500 an put it into the T400? Will i get the famous 1802/1804 error? Or should it work....

Thanks for your help!

It should work, provided you have SIM slot and required antennas in your T400.

yes, my T400 should have the antennas and a sim-card slot

Just came across this thread and can confirm the WWAN card from an SL300 is working fine in my T400 too.
