hai reddy,

Hey couldn't get back on time. I am yet to buy that USB modem. I will get back to you as soon as i get that device. The modem which i am planning to use looks like a pen drive. In that device i have a small slot in which i will be inserting my sim card. The doubt that still exists in my mind is

1. How do we connect to this particular device from our .Net
2. If we are able to establish the connection then, how do we interact with the SIM card that is inserted in that device. Is that possible?
3.How do i send messages from my pc to this device and then let that message pass through my SIM card to other users

Is this possible?
please get me a reply

Hello karthik

As of now i am using rs 232 (serial communication) that is 9 pin connector which comes default for your pc .when modem is considerd i am using wavecom modem
there may be a possibility for connecting through USB also but i have never worked on that .

if you are going to use 9 pin i will some links regarding connections an when coming to .net communiocation with modem use can use io ports name space

its not a big problem for just sending and receiving messages .but some constraints you hav to maintain almost every goes fine if you follow the link wat i hav posted earlier

hi reddi,

I am new to this field. I couldn't get what you where saying like what you mentioned above""rs 232 (serial communication) that is 9 pin connector "". I am absolutely new to this field. You just search for this stuff " Falcom SAMBA Modem" this is the device that i am planning to use. You just search for this in google and then tell me whether i will be able to connect with device using .Net. Hoping that you will help me complete my project. This is the main part of my project. If i am not able to connect means my project is going to be a failure.

Or can you suggest some other device through which i will be able to send SMS mainly bulk SMS without any delay. Please help me solve this. Expecting your reply

With the modem only u can't. There are many SMS web services available. Try to use that.

:)

Hey, I just happened to pay a visit to this thread. I have a similar need; but, I have no modems etc. And I use ASP.NET... is there any web service as you say that helps me send sms for free (worldwide)? if you do know please post a reply or PM me. Thanks in advance.

[Jimmy611]

Ok karthik i will email you the code snippet and you can refer to it. Its not for ASP.net application. Its done for windows application. But i am sure you can change it as per your need.

Hi Hkarthik,

The project i am doing is an IVR project which inculdes many modules and each of these modules are developed using different platforms as well .
Now i think the common module we have here is the problem of sending SMS.

I have a device named GPRS modem in which there is a slot to insert sim from which we can send sms .
Now next we need to use this modem within our application to send sms .

From the company from where i got the modem, gave a demo application in VB and also 2 ocx which does the function of connecting the modem ,opening the port and then send msg .So with the help of demo application i used the ocx in asp.net to send sms .
