Al beat me to responding to this, but +1 on his comment. IIUC, the email-to-sms is definitely not for commercial use (as in an iPhone app), and is more for 1 to 1 type communications. If your client is looking to build a business around SMS communications, they need to make the investment to use the standard SMS platforms. --Jaren
