[NTLK] Which card phones work?

I'm interested in using My 2100 with my t-mobile cell service.

What I'm trying to figure out is which cards work with the Newton.

The Nokia Cardphone has been being talked about recently.

Which others work with the Newton?

Sierra Wireless PC AirCard 750?

Is there a list somewhere?
Do I just plug mySIM card into the cards?

I'm using t-mobile as my service.
