My guess is, you are only noticing the big, 'call mobile' icon. However, scroll down, and you will see the others listed. They are in a list format, when you click on them, you call, and if you click the small text icon, it opens a text. So yes, it does display them all, it may have just missed your eye.
One more thing, i have the Kin Twom, but their softwares between the 2 models are nearly identical, if not exactly identical. The only difference is, the Kin Onem has a smaller screen, which may just 'hide' these options unless you scroll down. So, give that a try.
