So I have Canadian VGN-SZ750 (or I think?)
I can't seem to find sim-card slot for my laptop. Thought it would be behind the battery? I have antenna and wwan led but where do I insert my sim?

The sim card slot is indeed behind the battery. The sim holder is moxt likely covered over because North American models did not come with a sim card holder. You can though remove the sim card slot cover and also change your wwan card if need be.

You need to solder a sim card holder to WWAN daughterboard or purchase a EU wwan board. The wwan board is an IFX473.
If you take a look at the second picture in this auction you'll see it has the contacts for the sim holder but no sim holder.

You can use the wwan service as is on the EVDO networks.
This appears to be an EU board
