I dont have any experience with hardware, but have developed using Ericsson's Parlay X libraries and they are very easy to use: http://www.ericsson.com/mobilityworld/sub/open/technologies/parlayx/tools/telecom_web_services http://www.ericsson.com/mobilityworld/sub/open/technologies/... Its a useful library if the service provider you're trying to gain access to exposes Parlay X access to their network. Very easy to send/receive SMS, MMS, etc from your web application as they library wraps all the SOAP calls for you.
