Check if Your phone is supported by the PC Connectivity SDK and the connection method at the Connection Methods web page (http://forum.nokia.com/main/1,6566,1_55_30_20,00.html) or in the documentation (http://forum.nokia.com/main/0,6566,1_55_20,00.html).
There are sample applications installed with the SDK.
Depending on the phone model check out these examples: Messaging, SMS Edit, SMS Settings.
