Mobile connectivity and SMS sending

hi,

I am looking for an API for connecting my cell phone to PC and send SMS through it.i have no idea how it is done. if any one knows how it is done please share with me.thanks!

AFAIK there isn't a Java API for that, unless the manufacturer of your handset has provided one. You would need to use a communication API (RXTX?) and send the AT commands to the phone, which the PC commonly sees as a GSM Modem.

This suggestion does depend on you cell phone model and OS; a Windows Mobile device isn't seen as a modem by the computer it's tethered to.

It may be easier (and cheaper) to use a SMS gateway service.

what about COM port is it of any use???

There is no standard observed by manufacturers of mobile phones that would govern PC-to-mobile communication, including sending SMS. Most mobiles I've had in recently had an accompanying software that allowed me to write SMS on PC and send it via the phone. So it is doable, maybe even from Java (using JNI certainly), but it will be manufacturer- and probably even model-specific and you'd have to obtain the specification for the communication somehow. That might be the hardest part actually.

Lots and lots of hard work for little value, I'd say.
