You need to have a Registry Editor in this procedure:

For this guide our target would be the right soft key with the value 113. (left softkey is 112)

1. Download LNK.ZIP and copy Compose.lnk file to \Windows
2. Using ur Registry Editor goto "HKEY_CURRENT_USER\Software\Microsoft\Today\Keys\113"
3. Change the "Default" value to "Compose"
4. Change the value of the "Open" to "\windows\compose.lnk"
5. Save the modifications


LNK.zip contains:
Compose.lnk
19#:MSINBOX -service "SMS" -to ""

Balance.lnk (Smart Buddy Balance Inquiry)
19#:MSINBOX -service "SMS" -to "214" -body "?1515"
