Sorry if it's too offtopic, but pouet is the only place in the internet that I use to communicate with other developers.

The problem:
I'm looking for some kind of device to read a SIM Card with the capability of connecting itself on the cellphone network and sending SMS's programmatically. Any hint about the existence of such thing? I have no idea how to do it.

Sounds like you are looking for a mobile phone :p

I think any post-2004~ nokia phone with the PC suite installed is capable of doing this. I've even had a software for iPhone installed once that was capable of doing this as well.
Getting such a phone should be really cheap.
The iPhone sender was a 3rd party thing, so coding your own sender interface for it is doable.

Just find any cheap Nokia phone which can connect via USB and is supported by PC Suite, I was using Nokia 6267.
Then download Gammu application, configure it and you can send SMS's from your app like this:
ShellExecute(0,"open","gammu.exe","sendsms TEXT ******* -report -text \"**************\"",0,SW_SHOWNORMAL);

Take a look at this project,might be of interest to you : http://www.elektronika.ba/563/sms-box-project/

yes.. use an old phone and maybe a serial port driver bridge if it has usb interface.. then you may send sms by opening the COM port and communicate with it using ASCII..

Thanks for the reply.

oasiz: And I was all the night like: "I really hope I had specified it sufficiently".

Nitro: It's a nice solution. :)

D-Force: Yes, sounds interesting, I will read it soon.

hooverphonique: But I still wonder how the communication is done. :(

why use a phone at all, and not some online sms service provider? it's bound to be cheaper.

if you can use the phone as a modem (serial over bluetooth or usb) you can type standard hayes (at kind) commands into the phone. You can make and receive phone calls this way and send and receive text messages. I did this trick to send 1000 text messages once.

Sound funny but cell-phones do have an at command set

1. Go to the sparkfun website. (www.spakrfun.com)
2. order one of these tiny one square-inch GSM module with UART for less than 40€
3. Connect to your computer and send SMS via good old AT-commands.
4. PROFIT

I'm paying 50 cents for unlimited number of sms's per day. :) So I'm planning to conquer to world with that. ;)

what, that rapper dude is sending sms's for you?!

hayes command set is more or less standard (i guess some phones may deviate)..

buying a gsm module is an option, but an old phone is free ;-)

Busy sending sms for you. He looks kinda nerdy here.

lol :z

Mmm... I've never coded such hardware things. And I am still wondering how I can open the USB device through fopen on Windas :( I couldn't find any useful material for reading.

I need some help here. :/

use libusb

Thanks
