TMsvEntry functions and members used in SMS service entries in Using SMS

Settings for an SMS service are primarily stored as a CSmsSettings object in a stream in the CMsvStore associated with the service entry. Some data is stored in the service TMsvEntry entry to make that information easily and quickly available.

The table below describe the functions and member variables for TMsvEntry that are set by the MTM for an SMS service:

`TMsvEntry` member	Description
`Connected()`	Set by the SMS MTM to `EFalse` when disconnected from the service centre; set by the SMS MTM to `ETrue` when connected to the service centre.
`Description()`	Not normally used (because the SMS service is normally invisible to the user)

`iMtmData1`	Not used
`iRelatedId`	Not used
`iType`	Set to `KUidMsvServiceEntry`
