I opened it up to take a look at the mini-PCIe region and there isn't a WWAN slot available.
So i guess WWAN is definitely out the question.
The only thing i don't understand is the presence of the protruded WWAN antenna since WWAN isn't available on my particular unit...

Thanks for your reply.
I will open it up to take a look.

I don't think its a plug-in type, rather it has to be soldered. This is exactly how the SIM area looked like, on my notebook http://img5.ranchoweb.com/images/dubloboy/x61memorybaywithnosim5C27slot5C27.jpg Those with the SIM reader will look like this http://www.technologyguide.com/wp-content/uploads...

Thanks for your reply.
Since it does not have the SIM card reader soldered on the motherboard, can it still work?

Hi! I got a Thinkpad X60 (1706-C92) lying around in my drawer for quite sometime, as my secondary notebook. There is a WWAN antenna available at the top right corner of the LCD display. However, there isn't a SIM card reader available (SIM placeholder available on motherboard) besides the DIMM slots...
