What this does is it collects the information from what you put in when you click the "send" button. It moves this along to a processer, which transmits it along a dial up connect, which is then sent via a telephone company (not sure which one) and trasmitted to the cell phone. The cell phone picks it up as an ordinary text message.
The cool thing is is that you do not have to pay for text charges (if any apply). However, we are not sure the person at the other end has to pay. You are using this item at your own risk.
