Cannot help you on this.

AFAIK These cards (at least those I've played with) have common UARTs
and use PPP to connect, so In windows you should be able to capture
from NDIS_WAN as you would do with a normal modem call. (you'll see
the IP traffic the windows machine sends/receives).
If you want to use it as an air sniffer just forget about it, the
GSM/GPRS chipsets they have are consumer-grade that means they get
their channel and just stick to it. You won't even see the air
interface's control not even for itself. A system that actually does
air sniffing on GSM/GPRS networks costs at least three zeros more than
a consumer-grade GPRS card. And, AFAIK, in most countries these are
sold omnly to law-enforcement agencies (I'm aware of Italy and UK).
