It isn't Android, and it actually isn't a smartphone. So while no this actually isn't the right place (per the forum) for the post, I know a bit about these phones. So...
Do you mean to have the display of items show on the home screen (where the wallpaper is) all the time? That isn't possible on these devices. The screen can only hold what is already programmed to it.
The screen should already show the time (including minutes) and date (including the day of the week). Texts are only seen once opened. You can't see them prior to that. Nor is there a way to make them auto open. However, when you have any new texts it does show an icon on the upper left of the screen. The same for missed calls or new voice mails.
There would be no way...
