Best I got (in the UK) was 3p a text when I looked nearly 2 years ago. 
This was to an outfit in Scotland - you connect via an internet enabled 
API (ie. a bit of PHP code) and send the text via their service centre (or 
texts - I was looking at 2-4000 a month, but they went up to half a 
million a month).

What I do these days is use a Siemens GSM modem - with a SIM card in it on 
a PAYG tarrif (my needs are minimal right now) Linux supports sending SMS 
messages via getsms and putsms (which works in the pager section of 
voicemail.conf)

Sending TXT messages to a VoIP phone is going to be challenging, I 
think, but I'd like to think it is (or might be) possible!
