Hi

i heard that i can send sms from my pc using my cell phone . Then use the computer / PC and AT commands to instruct the mobile phone or GSM/GPRS modem to send SMS messages., does anyone know anything about this.

What is these AT commands and how do i setup the whole thing to work.

Thanks

Yes you can send SMS from many mobile phones using your PC. But not all mobiles support that. You will have to check by connecting the mobile to your PC using its data cable and trying the command AT on it using hyper terminal.

There are many AT commands.

To send SMS you can can use

AT+CMGS=<number>
<message>ctrl+z

To read sms from inbox you can use

AT+CMGR=<address>
address is the location number, can be 1, 2... etc.

There are commands for almost everything you can do with the phone.

Before attempting this make sure that you are skillled in serial port programming.

HI

Can I do this with a c# code in an ASP.NET web application. I want the sms to be sent from my web application. Is it possible and if yes, can you please give me the code snipet for doing this.

Do i have to pay anything for using the bulk sms gateway. and how do I use it? Sorry to bother you so much but i really have to do this urgently.

Yes my dear, the idea is that you buy bulk smses and use your account in sending the smses. I personally use intellisoft's gateway(s). See a similar post i did just today.

Further questions? get back to me.:cool:

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 <snipped>.
