Enabling Enhanced Messaging Service (EMS) Processing
When Windows Mobile boots, it checks the system registry for the following key:
HKEY_CURRENT_USER\Software\Microsoft\SMS\TextShared
This key contains a flag that specifies whether EMS processing is enabled on the device. EMS processing is disabled by default, however, you can enable this support yourself.
To enable EMS processing support:
Register the COM component's GUID by creating the following registry key, and giving it the following name/value pair.
HKEY_CURRENT_USER\Software\Microsoft\SMS\TextShared DWORD : EMSHandlerInstalled = 1
