Hello,
Firstly Paradigm Shift is not a Responsive Template so it will display content on mobile devices much differently. If you are looking to add mobile only content you can do this under the mobile tab in the Template Manager.
Here are the instructions from the tool tips and the available mobile positions:
Below you may setup mobile device support for your website. Your menu will be pulled from the same menu set in the Menu Options area. The mobile version contains the unique module positions mobile_top_1, mobile_top_2, mobile_bottom_1, and mobile_bottom_2, you may publish any module to these positions and they will only show on the mobile version.
Module positions: logo, search and breadcrumb are also present but are shared with the main PC version. Disabling the show frontpage article/component area in General Options will also disable the mobile version's frontpage area.
