Well here is a device that could be very important for you. Its the Z-text sms modem. A usb device with windows drivers and software to let you test the capabilities of the unit – the Sms modem can be installed in a few minutes.
Once installed you can send your first SMS immediately since the BT service allows you to “register” by actually sending a message.
