Obviously, LV itself can't send an SMS message. You need a device connected to the cellular network to do this. So, you need to talk to that device. There are several ways - use LV to connect to a web site offering this and send the message through that site, use a cellular modem which accepts serial AT commands and connect it to the computer or use a cellular modem with a DLL interface. Which path do you want to take? If you have no hardware for this, try searching google for GSM toolbox. It's supposed to be a collection of VIs which let you do this.
