I have 2 short-codes through twilio and the 30-40% cheaper SMS rate grabbed my attention. I love twilio and never managed to get far when trying to figure out how to go direct to the carriers and get better pricing (and twilio was never interested in price negotiations, in fact I serve mostly non-profits and they wouldn't even give me their non-profit pricing). But with pricing pressure from plivo, maybe I can make some progress.
