FrontlineSMS [http://www.frontlinesms.com] is a desktop software that lets you send SMS with the use of your mobile phone’s modem features. Prior to installing FrontlineSMS, I was using a Nokia 30 GSM modem with a software the comes with the hardware. But, the problem with the Nokia 30 is that I need to insert my SIM card to it every time I will be sending messages (i.e. billing reminders) through my PC. Now, with Frontline SMS, all I need to do is to attach my mobile phone via USB to my PC and fire up the app.
