message. Launch the console by choosing File > Utilities... from the KToolbar
menu. Click on the Open Console button in the WMA box to launch the WMA
console.
Click on the Send SMS... button in the WMA console window. Choose the number
that corresponds to the emulator, probably +5550000. If you're not sure what

message and click on Send.
