hey there i would also like to build a site in similar charistics but i would like to build a site more like send horoscopes to cell phones for $2 a text question ect . if you know what i mean but if any one has ideas on how to start one please responed asap

You'll want to hook into a 3rd party company that is already integrated into the major wireless providers' billing systems. www.golivemobile.com is the biggest one I know of. Just a heads up though, the majority of premium sms services are irritating scams. If you build one of those scam services, a lot of people (myself included) will not like you.

I want to make a site for free SMS service in INDIA. This website will have
the capability to send sms to mobile phones(i.e Web to Mobile SMS Service).
I think, We require a SMS Gateway for this purpose.

Please help me in creating sms gateway. reply me to intechserver@gmail.com

Hi friend...I have been into this SMS gate way stuff ..I used many sms gateways like OZEKI ,Mcore etc. ...But the problem is all of them are paid softwares and so it does have limitations.So i tried making an sms gateway of my own and by gods grace i succeded.I used Serial port communication using c#.net and AT commands for communicating with the modem. ..Its working perfectly for me.I can send and receive sms using this ... I put some tutorials in my website
<URL SNIPPED>

I know this tutorial is not complete,but it covers the most tedious task i faced,ie to convert text message to PDU format which most mobile phones recognizes. The rest is not that tough

I can get you the code if you need.Please contact me ...
Or else if u prefer using OZeki ,here is the tutorial for using those kind of stuffs
