IASP was a pioneer in the web-to-SMS space. We have operated a dedicated SMS gateway since 2003 and continue to offer integrated SMS via the built-in messenger system within our websites along with a stand-alone web-to-SMS service via our smsport.com.au website.
Over the years we have become acutely aware of the severe limitations of the SMS protocol in the practical commercial environment: an 11-character header limit, a 160-character message limit, the high cost per message, and the unreliability due to network incompatibilty all combine to make SMS likely to be consigned to the same fate as Beta Video and Digital Cassettes.
These technologies had their time in the spotlight, but the new generation of mobile e-mail and mobile Internet overcome most if not all of SMS's limitations and are destined to replace SMS as the preferred web-to-mobile communications platforms.
At the risk of sounding melodramatic, the mobile Internet revolution could see the biggest upheaval in the industry's brief history; very few players are prepared -- for example Google is fully Internet-ready for mobiles, while Telstra products such as WhitePages are, apparently, not.
