SMS Gateway
I have yet to try them out, but Clickatell seems like a nice, developer friendly SMS gateway.
UPDATE:
They offer a trail account where you get a few messages for free (although they override the message content with a default text), so I couldn’t resist and tried it out.
It’s really a matter of minutes if not seconds to get started:
schmidp@dna:~$ curl -i “http://api.clickatell.com/http/sendmsg?user=$USER&password=$PASSWORD&api_id=$APIID &to=$TO&from=$FROM&text=$TEXT”
HTTP/1.1 200 OK

I have not yet compared their prices with other gateway providers, but I don’t have a real need for it now.
