We've been using OpenVox G400P cards  (PCI; there is also a G400E, which is 
PCI express for newer motherboards).  Sends and receives text messages, and 
makes and answers phone calls.  Accepts up to four RF modules, each of which 
accepts one SIM card.

If you only need text message functionality  (not voice calls),  then almost 
any old mobile phone with a USB or RS232 cable can be used as a GSM modem -- 
and you probably have one lying in a drawer.
