Can't create messages / no messaging app

When i turn the bezel left, I can online read and answer to received messages. If there are no messages, I am not able to create one, as the three dots on the right site are missing. Also going into the list with all apps, there is no messaging app. In the manual it is displayed and described differently.

Is this the same for everyone? Or something wrong with my device(s)?
