Okay, thanks for the insight. Although I'm still wondering what volumes of messages you are pushing to get a 1cent/message rate. Last time I checked even large scale contracts (>10k messages/day) would be billed at least five times that amount. Plus fixed fees...
We are not abusing e-mail or web interfaces. We spent months getting contracts set up so we could access the same data that major cell carriers use to route their text messages.
For one cent a message, give it a try, I think your concerns will be remedied :)
