I need to send SMS to mobile phones from vb application. is it possible to send SMS without internet connection, only with a modem. give me some solution to do this. if it is not possible to send SMS without internet, then give me a solution with internet. Or if we can send with MScomm control and Modem please give me that solution
Well i am not sure how to do this, but i know it is possible i saw some apps to do this . try searching planet source code ( http://www.planetsourcecode.com ) and look over there... maybe somebody has created a similar thing.
my colleagues tried that last year but with limited success....
nokia fones don't respond to raw at+commands right? how bout using an ericsson or siemens fone... it will simplify your design greatly because nokia fones have thier proprietary codes (which is conveniently not available ) while at+commands are freely available. i am by the way planning to work on a similar system....
they didnt use vb in their project, actually it wasnt even based on a pc but on a microcontroller system. what they didnt realize before is that they need to install some nokia drivers so the fone will obey the at commands. at present im working on a pc-based system and have installed the necessary software. i can control my 5110 through hyperterminal. my only hurdle now is making a hyperterminal-like program in vb. i'm done with the sending part, my problem is on receiving the fone's reply. seems my oncomm handler isnt working so fine yet... anyways hows your project going?
after browsing the forums i think i've figured out whats wrong with my code ,i'm gonna try it tonight. hey philip, your post is interesting... so how exactly do we use simplewire.com to send the sms? thanx in advace.

They provide an activex control that you can use to easily send a message. Really easy to use, but again, it's kinda an expensive alternative. Although, they do have massive network support
so its expensive? then that rules out the simplewire.com alternative hehehe... i guess i'd stick to the original plan of connecting a gsm fone through the serial port. it's simpler and cost effective (since i'm not expecting very heavy sms traffic anyway). thanx for the info.

btw, where can i find sample code on interfacing a modem?
thanx for all peeps who gave me much needed input and advice on my project. finally its done! i interfaced a 5110 to a PC and my program automatically responds depending on the message it receives. anyway, thanx again!
I have a nokia 3210, old i know, but does what i want, i also have a cable to connect it to my pc.
And im interested in this kind of thing that you are doing, but how would i write a program to connect to the phone? What do i need? any specific API's? ocx? etc etc
Another alternative to the simplewire activex control is to download Nokia's PC Connectivity SDK V2.1 which contains their DLL's to communicate with the phone. It has examples that show you what to do. I have already written a simple VB project to send SMS with it, but at the moment I can not find it to post it but when I do I will.
A note for Sonya_79, you mentioned that your friends where trying to implement their project in a microcontroller. The reason for me trying to make a VB project for SMS is to study the communications between the PC and phone and try to achieve the same results in a microcontroller.
Is it possible to find out more info about this project of theirs?
