When the OS 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
    

Remarks

EMS is defined in 3GPP Technical Specification 23.040 "Technical realization of Short Message Service (SMS)". It can be obtained from this website https://www.3gpp.org/ftp/Specs/html-info/23040.htm.
