Delete Messages on Session End

 Enables the radio to delete all TMS (Text Messaging Service) messages from the Inbox, Drafts, and Sent Items folders when the current user session ends with the server. Session end scenarios include: user-initiated logout, radio power-down, registration failure, server-initiated logout, and changing or clearing the Username via the Soft ID Feature. This feature applies for all Data Profiles and for both Automatic Registration Service and User Authentication communication protocols.

 When disabled, the radio-user is prompted with the option whether or not to delete TMS messages upon manually logging out via the User Login feature. If the login session ends for some other reason (such as cancelling a login process or a server-initiated timeout), then the TMS messages are not deleted (there is no user prompt).
