contact a service provider, they'll have APIs for you (at a price).

Thank you, but the problem the service provider they offer applications, but I need a code to add it to my software. I am going to add this sms code to my main code, so do you have any suggestion?

> but the problem the service provider they offer applications,
Find out more about what they offer, read some documentation.
Maybe it's all done through a nice DLL you can just link to.
Or maybe it's a simple command line program where you can do "sendSms number message", which would be dead easy to use from your code.

If you talk to the consumer helpdesk or salesrep, they will indeed give you (or sell you) a ready made piece of software (which is what mom and pop want).
You'll need to dig deeper, or maybe go to a specialised company, to get an API.

Thanks Salem and jwenting, I will contact my service provider...
Also I am thinking to use visual because it is easier to send sms using a GSM modem and I will connect the C++ and visual codes together...
Thanks again...

please give me the suggestion and cheapest way(cost) for sending sms from computer (linux)to mobile for project? and also we need code for that urgently

I've used the old Ericsson mobiles to read contents of SIM cards and to send/read SMSs. The commands are sent to the mobile using your serial port at 9600,n,8,1 - you will need to convert the RS232 level (+/- 10 volts) to TTL level (0-5 volts) - can use MAX232 or some transistors & resistors - or you can use a ready made cable (don't know where you'd get it - maybe eBay).

Then send serial AT commands to the mobile, as detailed in:
http://www.usbdeveloper.com/GSMPage/gsmpage.htm
(there may be some Nokia commands here also?)

Old Nokia phones can be used in a similar manner. I assume a different command set is required. Check out www.siliconchip.com.au as they have some projects on using Nokia phones for sending/receiving SMSs.

Simple!
