You need a suitable GSM card.  We have used the OpenVox G400P / E400E series.  
This has a facility for sending SMS directly via the Asterisk CLI  (and hence, 
any programming language that can issue a system() command).  It can be 
obtained with up to four GSM modules, which are also available separately if 
you need to upgrade a card with only one, two or three.

Note that whilst every telco will promise you "unlimited text messages" on 
their SIM-only, pay-monthly contracts, in practice, they will cut you off for 
bogarting bandwidth in a heartbeat if you send too many messages too quickly 
for too long at a stretch.  What that actual limit is, seems to be a secret 
more jealously guarded than the Windows Source Code; and the easiest way to 
find out seems to be to exceed it.
