In order to develop SMS gateway you would need to connect to wireless carriers' networking using SMPP or HTTP api.

For developing SMPP client, refer to SMPP specifications which was published by logica open source created in java. You would need to convert that to .net sockets.

It'll take too long to develop SMPP client, alternate you can use http api from sms aggregators such as http://www.wire2air.com, http://www.txtimpact.com or mcube, etc.

Thanks

Let me try and answer your questions.

Do you need to receive SMS? If you need to receive SMS, you will need to host your own GSM device or modem so that people can send you SMS.

If not, you can just use internet SMS gateways like clickatell to do the work, and post to them by HTTP, XML or email. The cost is about 6-8 cents per SMS. There are cheaper services, but not always reliable. If you need to host your own GSM device, you can use software like http://www.kannel.org (GPL Open Source) or http://visualtron.com/enterprise/sms-gateway.

If you still haven't found an SMS gateway, you can have a look at Ozeki software. You can use it from ASP.NET. It works with GSM modem but if you use it with IP connection, the capacity can be really high. For more info of how Ozeki works with ASP.NET, visit: http://www.ozekisms.com/index.php?owpn=230
