I have an Ubuntu server and i have a SIM card (sorry for bad English) which has monthly 10,000 SMS .
Now i need to send SMSes on my project. Is it possible to use my mobile phone (Nokia 5800 and USB cable) and my SIM card for sending SMSes on my project ?
I'm developing it with PHP . And i have my own server so i can install everything.
Some mobiles can present themselves as a serial port (ttyUSB or ttyACM). You can then use variants on the AT command set (as if it were a modem) to send and recieve SMS messages. You could do this by hand, or you could hook into utilities like gsmsmsd to simplify the process.

Probably best option for you is gnokii:

You can use it with PHP, Ruby and Perl.
Have Fun!
