Dear all,

my company just acquired R400 for most of the staff here. Prodcut type is 7443-TGA. On specs at lenovo.com says it has WWAN upgradeable.

Can we buy some WWAN module and install it on the laptop? Or it have to be done by service center?

Thanks

I just upgrade my R400 to WWAN ready.
I purchase the SIM slot, antenna & WWAN card from eBay and install by myself.
Most of R400 are without SIM slot and 3G antenna, maybe you can order R400 with SIM slot & antenna directly from lenovo.

Hi,

Just wondering did you get the clear plate kit for R400 with the WWAN logo? from the Lenovo documentation I can see there are 2 part numbers but I am not sure which one comes with the WWAN logo.

regarding the antenna cable, do you have to dismantle and detach the entire screen from the hinge? or just remove the cover but leave the screen on the hinge?

thanks

Benjamin
